Abstract :
This paper considers system performance with a causal noise whitening filter and shows that at 50 Mbit/s the sensitivity is within 0.5 dB of ideal detection and 6.7 dB better than PCM. A 565 Mbit/s system is also considered and it is demonstrated that to allow operation at this bit-rate the cut-off frequency of the noise whitening filter must be greater than the noise corner frequency so as to reduce pulse dispersion. The results predict that the PIN-FET PPM system should offer an improvement of typically 6 dB over an equivalent PCM system
