Optimal and suboptimal performance of a PCM/FM communication system
Abstract
Theoretical results are presented on probability of error in the detection of binary FM signals for various frequency deviations with fixed bit rate, restricted predetection filter bandwidth, ideal limiter-discriminator reception, and integrate-and-dump postdetection filter decision. The results show that suboptimal system performance can be achieved by choosing the largest possible value of deviation index which lies approximately at 0.7 + 2n, where n is an integer determined by the reconstructability of signal after the bandpass filter.
