Replace all of the text in the subclause before Figure 13 by the following:

For each subcarrier period:
— Ø is defined as the argument of all differences between sections in the occurrence of MS1 and the
LM
corresponding sections in the occurrence of MS2 in the same subcarrier period, as illustrated in
Figure 13;
— there is an absolute maximum and an absolute minimum of Ø ; Ø’ is defined as the one which
LM LM
occurs first in time, Ø’’LM is the one which occurs secondly, then
ΔØ = Ø’’ – Ø’ ;
LM LM LM
— with Ø being the maximum absolute difference between Ø’ and any Ø occurring before Ø’
LM-le
