CISPR 21:1985
(Main)Interference to mobile radiocommunications in the presence of impulsive noise; methods of judging degradation and measures to improve performance
General Information
- Abstract
Numerous test programmes have been conducted using voice transmissions in an attempt to develop a simple, objective measurement which would correlate well with the subjective effects of mobile radio degradation; the results have been partially successful. This CISPR Report summarizes the conclusions which have been reached, gives suggestions for mobile receiver design, and proposes the need for world-wide receiver noise immunity specifications.
