Digital Video Broadcasting (DVB) - Next Generation broadcasting system to Handheld, physical layer specification (DVB-NGH) - Part 2: MIMO Profile

The present document describes the next generation transmission system for digital terrestrial MIMO broadcasting to
handheld terminals making use of multi-aerial structures at the transmitting and receiving ends. It specifies the
differences of the MIMO Profile physical layer part to the physical layer part of the Base Profile ETSI
EN 303 105-1 [1] - from the input streams to the transmitted signals. This transmission system is intended for carrying
Transport Streams or generic data streams feeding linear and non-linear applications like television, radio and data
services. DVB-NGH terminals might also process DVB-T2-lite signals.

Digitalna videoradiodifuzija (DVB) - Radiodifuzijski sistem naslednje generacije za dlančnike, specifikacija fizične plasti (DVB-NGH) - 2. del: Profil MIMO

Ta dokument opisuje sistem prenosa naslednje generacije za digitalno prizemno radiodifuzijo MIMO, namenjeno ročno upravljanim terminalom, pri čemer se uporablja več nadzemnih konstrukcij na oddajnem in sprejemnem koncu. Določa razlike med delom fizične plasti profila MIMO in delom fizične plasti osnovnega profila ETSI EN 303 105-1 [1] od vhodnih tokov do prenesenih signalov. Ta sistem prenosa je namenjen prenašanju transportnih tokov ali splošnih podatkovnih tokov v linearne in nelinearne aplikacije, kot so televizija, radio in podatkovne storitve. Terminali DVB-NGH lahko obdelujejo tudi signale DVB-T2-lite.

4 DVB-NGH MIMO system definition
4.1 System overview and architecture
4.1.1 Overview

MIMO transmission options are included in the optional MIMO Profile - reflected by the present document - in order to

exploit the diversity and capacity advantages made possible by the use of multiple transmission elements at the

transmitter and receiver. Channel estimation suitable for MIMO is provided by an appropriate pilot structure, identical

to that provided in the Base Profile ETSI EN 303 105-1 [1] for MISO frames. The term 'MIXO frames' encompasses all

frames containing such pilots. MIMO may hence form part of a transmission including MISO PLPs as well as SISO

frames as defined in the Base Profile [1]. Within MIXO frames, different schemes may be applied to constituent PLPs

according to the desired transmission characteristics; for instance MISO is specified for L1 signalling and may also be

used for any other low-rate high-robustness transmission. Rate 2 MIMO, which increases the data multiplexing rate by

sending distinct information from each transmit element, can be chosen where high data throughput efficiency is the

primary goal.

In the following clauses, the differences to the Base Profile ETSI EN 303 105-1 [1] are outlined with reference to their

Base Profile [1] counterparts.

Compared to the Base Profile [1], only the BICM and the OFDM generation stage contains functional differences.

NOTE: Blocks differing from the Base Profile ETSI EN 303 105-1 [1] are shaded to grey.

Figure 3: Bit Interleaved Coding and Modulation (BICM) with mixed MIMO and MISO PLPs

4.1.3 FEC encoding and interleaving inside a FEC block

MIMO PLPs within the MIMO Profile - reflected by the present document - employ a revised bit interleaver intended to

simplify iterative MIMO decoding at the receiver. The Base Profile ETSI EN 303 105-1 [1] bit to cell demultiplexing is

no longer explicitly present.
4.1.4 Modulation and component interleaving

The constellation is non-rotated QPSK, 16-QAM and 64-QAM. The constellation may be the same or different on the

output MIMO pair depending on the chosen operational mode.
4.1.5 Time interleaving (inter-frame convolutional interleaving plus
intra-frame block interleaving)

Since the time interleaving is carried out after the generation of two MIMO streams there are two parallel time

interleavers. The time interleaving applied to both MIMO streams is identical. To keep the total memory requirement

the same, each of these MIMO streams has half the maximum depth as the Base Profile [1].

4.1.6 Frame building, frequency interleaving

MIMO frames are built according to figure 4. This is the same architecture as the Base Profile [1] except for the

allocation of space for the aP1 symbol.

The frequency interleaver is a pairwise interleaver defined in Base Profile [1], clause 9.10.

Figure 4: MIMO Frame Builder
4.1.7 OFDM generation

The ACE PAPR technique cannot be applied to frames of preamble format "NGH-MIMO".

Figure 5: OFDM generation
5 Transmit/receive system compatibility

To make use of the MIMO Profile reflected by the present document, the proposed transmitter hardware shall include

individually-fed cross-polar antennas (Horizontal (HP) and Vertical POLARIZATION (VP)). In addition, to receive and

decode the MIMO signal, a cross-polar pair of antennas is necessary at the receive terminal.

In a given PLP, only one of MISO or MIMO encoding may be used, i.e. they are not cascadable.

The bit interleaver for the MIMO Profile described below in clause 6 is a replacement for that described in ETSI

EN 303 105-1 [1].

6 Bit interleaver

The bit interleaver used for MIMO PLPs is different from the one used in the Base Profile [1]. Figure 6 shows the basic

block diagram.
Figure 6: Bit Interleaver of the MIMO Profile

In order to allow for a more efficient receiver implementation, the new bit interleaver is adapted to the quasi-cyclic

structure of the LDPC code. The new bit interleaver for MIMO consists of two components: a parity interleaver and a

parallel bit interleaver.

The parity interleaver is identical to the one used in the bit interleaver of the Base Profile (see ETSI EN 303 105-1 [1],

clause 6.1.4). Its role is to convert the staircase structure of the parity-part of the LDPC parity-check matrix into a quasi-

cyclic structure similar to the information-part of the matrix. At the output of the parity interleaver the LDPC codeword

consists of 45 adjacent Quasi-cyclic Blocks (QB), each block consisting of 360 bits (note also the Q parameter in

ldpc

ETSI EN 303 105-1 [1], clause 6.1.2). The parity-interleaved codeword is interleaved by the parallel bit interleaver and

then mapped to a sequence of Spatial-Multiplexing (SM) blocks of N bits each, as shown in figure 7 for N = 8.

QB 1 QB 2 QB 3 QB 45

Parallel Bit Interleaver

Figure 7: Parallel bit interleaver, QB and section interleaver part

The parallel interleaver in turn comprises two stages: a QB interleaver and a section interleaver.

The QB interleaver permutes the order of the 45 Quasi-cyclic Blocks (QBs) of the LDPC codeword. The corresponding

QB permutation is optimized for each combination of N , code rate, and power imbalance. Tables 1 to 3 show these

bpcu

permutations for N = 6, 8 and 10, respectively, each table containing the permutations for all code rates and power

bpcu
imbalances. The QB indices range from 1 to 45.

Foreword

This European Standard (EN) has been produced by Joint Technical Committee (JTC) Broadcast of the European

Broadcasting Union (EBU), Comité Européen de Normalisation ELECtrotechnique (CENELEC) and the European

Telecommunications Standards Institute (ETSI).

NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the

specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body

by including in the Memorandum of Understanding also CENELEC, which is responsible for the

standardization of radio and television receivers. The EBU is a professional association of broadcasting

organizations whose work includes the co-ordination of its members' activities in the technical, legal,

programme-making and programme-exchange domains. The EBU has active members in about

60 countries in the European broadcasting area; its headquarters is in Geneva.

The DVB Project is an industry-led consortium of broadcasters, manufacturers, network operators, software developers,

regulators and others from around the world committed to designing open, interoperable technical specifications for the

global delivery of digital media and broadcast services. DVB specifications cover all aspects of digital television from

transmission through interfacing, conditional access and interactivity for digital video, audio and data. The consortium

came together in 1993.

The present document is part 2 of a multi-part deliverable. Full details of the entire series can be found in part 1 [1].

EN 303 105-1 [1] - from the input streams to the transmitted signals. This transmission system is intended for carrying

Transport Streams or generic data streams feeding linear and non-linear applications like television, radio and data

services. DVB-NGH terminals might also process DVB-T2-lite signals.

4.1 System overview and architecture
4.1.1 Overview

MIMO transmission options are included in the optional MIMO Profile - reflected by the present document - in order to

exploit the diversity and capacity advantages made possible by the use of multiple transmission elements at the

transmitter and receiver. Channel estimation suitable for MIMO is provided by an appropriate pilot structure, identical

to that provided in the Base Profile ETSI EN 303 105-1 [1] for MISO frames. The term 'MIXO frames' encompasses all

frames containing such pilots. MIMO may hence form part of a transmission including MISO PLPs as well as SISO

frames as defined in the Base Profile [1]. Within MIXO frames, different schemes may be applied to constituent PLPs

according to the desired transmission characteristics; for instance MISO is specified for L1 signalling and may also be

used for any other low-rate high-robustness transmission. Rate 2 MIMO, which increases the data multiplexing rate by

sending distinct information from each transmit element, can be chosen where high data throughput efficiency is the

primary goal.

In the following clauses, the differences to the Base Profile ETSI EN 303 105-1 [1] are outlined with reference to their

Base Profile [1] counterparts.

Compared to the Base Profile [1], only the BICM and the OFDM generation stage contains functional differences.

NOTE: Blocks differing from the Base Profile ETSI EN 303 105-1 [1] are shaded to grey.

4.1.3 FEC encoding and interleaving inside a FEC block

MIMO PLPs within the MIMO Profile - reflected by the present document - employ a revised bit interleaver intended to

simplify iterative MIMO decoding at the receiver. The Base Profile ETSI EN 303 105-1 [1] bit to cell demultiplexing is

no longer explicitly present.
4.1.4 Modulation and component interleaving

The constellation is non-rotated QPSK, 16-QAM and 64-QAM. The constellation may be the same or different on the

output MIMO pair depending on the chosen operational mode.
4.1.5 Time interleaving (inter-frame convolutional interleaving plus
intra-frame block interleaving)

Since the time interleaving is carried out after the generation of two MIMO streams there are two parallel time

interleavers. The time interleaving applied to both MIMO streams is identical. To keep the total memory requirement

the same, each of these MIMO streams has half the maximum depth as the Base Profile [1].

4.1.6 Frame building, frequency interleaving

MIMO frames are built according to figure 4. This is the same architecture as the Base Profile [1] except for the

allocation of space for the aP1 symbol.

The frequency interleaver is a pairwise interleaver defined in Base Profile [1], clause 9.10.

4.1.7 OFDM generation

The ACE PAPR technique cannot be applied to frames of preamble format "NGH-MIMO".

Figure 5: OFDM generation
5 Transmit/receive system compatibility

To make use of the MIMO Profile reflected by the present document, the proposed transmitter hardware shall include

individually-fed cross-polar antennas (Horizontal (HP) and Vertical POLARIZATION (VP)). In addition, to receive and

decode the MIMO signal, a cross-polar pair of antennas is necessary at the receive terminal.

In a given PLP, only one of MISO or MIMO encoding may be used, i.e. they are not cascadable.

The bit interleaver for the MIMO Profile described below in clause 6 is a replacement for that described in ETSI

EN 303 105-1 [1].

6 Bit interleaver

The bit interleaver used for MIMO PLPs is different from the one used in the Base Profile [1]. Figure 6 shows the basic

block diagram.
Figure 6: Bit Interleaver of the MIMO Profile

In order to allow for a more efficient receiver implementation, the new bit interleaver is adapted to the quasi-cyclic

structure of the LDPC code. The new bit interleaver for MIMO consists of two components: a parity interleaver and a

parallel bit interleaver.

The parity interleaver is identical to the one used in the bit interleaver of the Base Profile (see ETSI EN 303 105-1 [1],

clause 6.1.4). Its role is to convert the staircase structure of the parity-part of the LDPC parity-check matrix into a quasi-

cyclic structure similar to the information-part of the matrix. At the output of the parity interleaver the LDPC codeword

consists of 45 adjacent Quasi-cyclic Blocks (QB), each block consisting of 360 bits (note also the Q parameter in

ldpc

ETSI EN 303 105-1 [1], clause 6.1.2). The parity-interleaved codeword is interleaved by the parallel bit interleaver and

then mapped to a sequence of Spatial-Multiplexing (SM) blocks of N bits each, as shown in figure 7 for N = 8.

Parallel Bit Interleaver

Figure 7: Parallel bit interleaver, QB and section interleaver part

The parallel interleaver in turn comprises two stages: a QB interleaver and a section interleaver.

The QB interleaver permutes the order of the 45 Quasi-cyclic Blocks (QBs) of the LDPC codeword. The corresponding

QB permutation is optimized for each combination of N , code rate, and power imbalance. Tables 1 to 3 show these

bpcu

permutations for N = 6, 8 and 10, respectively, each table containing the permutations for all code rates and power

bpcu
imbalances. The QB indices range from 1 to 45.

1 Scope

The present document describes the next generation transmission system for digital terrestrial MIMO broadcasting to

handheld terminals making use of multi-aerial structures at the transmitting and receiving ends. It specifies the

differences of the MIMO Profile physical layer part to the physical layer part of the Base Profile ETSI

EN 303 105-1 [1] - from the input streams to the transmitted signals. This transmission system is intended for carrying

Transport Streams or generic data streams feeding linear and non-linear applications like television, radio and data

services. DVB-NGH terminals might also process DVB-T2-lite signals.

4 DVB-NGH MIMO system definition
4.1 System overview and architecture
4.1.1 Overview

MIMO transmission options are included in the optional MIMO Profile - reflected by the present document - in order to

exploit the diversity and capacity advantages made possible by the use of multiple transmission elements at the

transmitter and receiver. Channel estimation suitable for MIMO is provided by an appropriate pilot structure, identical

to that provided in the Base Profile ETSI EN 303 105-1 [1] for MISO frames. The term 'MIXO frames' encompasses all

frames containing such pilots. MIMO may hence form part of a transmission including MISO PLPs as well as SISO

frames as defined in the Base Profile [1]. Within MIXO frames, different schemes may be applied to constituent PLPs

according to the desired transmission characteristics; for instance MISO is specified for L1 signalling and may also be

used for any other low-rate high-robustness transmission. Rate 2 MIMO, which increases the data multiplexing rate by

sending distinct information from each transmit element, can be chosen where high data throughput efficiency is the

primary goal.

In the following clauses, the differences to the Base Profile ETSI EN 303 105-1 [1] are outlined with reference to their

Base Profile [1] counterparts.

Compared to the Base Profile [1], only the BICM and the OFDM generation stage contains functional differences.

NOTE: Blocks differing from the Base Profile ETSI EN 303 105-1 [1] are shaded to grey.

Figure 3: Bit Interleaved Coding and Modulation (BICM) with mixed MIMO and MISO PLPs

4.1.3 FEC encoding and interleaving inside a FEC block

MIMO PLPs within the MIMO Profile - reflected by the present document - employ a revised bit interleaver intended to

simplify iterative MIMO decoding at the receiver. The Base Profile ETSI EN 303 105-1 [1] bit to cell demultiplexing is

no longer explicitly present.
4.1.4 Modulation and component interleaving

The constellation is non-rotated QPSK, 16-QAM and 64-QAM. The constellation may be the same or different on the

output MIMO pair depending on the chosen operational mode.
4.1.5 Time interleaving (inter-frame convolutional interleaving plus intra-
frame block interleaving)

Since the time interleaving is carried out after the generation of two MIMO streams there are two parallel time

interleavers. The time interleaving applied to both MIMO streams is identical. To keep the total memory requirement

the same, each of these MIMO streams has half the maximum depth as the Base Profile [1].

4.1.6 Frame building, frequency interleaving

MIMO frames are built according to figure 4. This is the same architecture as the Base Profile [1] except for the

allocation of space for the aP1 symbol.

The frequency interleaver is a pairwise interleaver defined in Base Profile [1], clause 9.10.

Figure 4: MIMO Frame Builder
4.1.7 OFDM generation

The ACE PAPR technique cannot be applied to frames of preamble format "NGH-MIMO".

Figure 5: OFDM generation
5 Transmit/receive system compatibility

To make use of the MIMO Profile reflected by the present document, the proposed transmitter hardware shall include

individually-fed cross-polar antennas (Horizontal (HP) and Vertical POLARIZATION (VP)). In addition, to receive and

decode the MIMO signal, a cross-polar pair of antennas is necessary at the receive terminal.

In a given PLP, only one of MISO or MIMO encoding may be used, i.e. they are not cascadable.

The bit interleaver for the MIMO Profile described below in clause 6 is a replacement for that described in ETSI

EN 303 105-1 [1].

6 Bit interleaver

The bit interleaver used for MIMO PLPs is different from the one used in the Base Profile [1]. Figure 6 shows the basic

block diagram.
Figure 6: Bit Interleaver of the MIMO Profile

In order to allow for a more efficient receiver implementation, the new bit interleaver is adapted to the quasi-cyclic

structure of the LDPC code. The new bit interleaver for MIMO consists of two components: a parity interleaver and a

parallel bit interleaver.

The parity interleaver is identical to the one used in the bit interleaver of the Base Profile (see ETSI EN 303 105-1 [1],

clause 6.1.4). Its role is to convert the staircase structure of the parity-part of the LDPC parity-check matrix into a quasi-

cyclic structure similar to the information-part of the matrix. At the output of the parity interleaver the LDPC codeword

consists of 45 adjacent Quasi-cyclic Blocks (QB), each block consisting of 360 bits (note also the Q parameter in

ldpc

ETSI EN 303 105-1 [1], clause 6.1.2). The parity-interleaved codeword is interleaved by the parallel bit interleaver and

then mapped to a sequence of Spatial-Multiplexing (SM) blocks of N bits each, as shown in figure 7 for N = 8.

QB 1 QB 2 QB 3 QB 45

Parallel Bit Interleaver
SM block SM block SM block SM block
1 2 3 4050
Figure 7: Parallel bit interleaver, QB and section interleaver part

The parallel interleaver in turn comprises two stages: a QB interleaver and a section interleaver.

The QB interleaver permutes the order of the 45 Quasi-cyclic Blocks (QBs) of the LDPC codeword. The corresponding

QB permutation is optimized for each combination of N , code rate, and power imbalance. Tables 1 to 3 show these

bpcu

permutations for N = 6, 8 and 10, respectively, each table containing the permutations for all code rates and power

bpcu
imbalances. The QB indices range from 1 to 45.
