A methodology for approximating BPSK demodulator performance in the presence of various undesired signals

Michael G. Cotton

Abstract: This paper describes a methodology for analyzing binary phase-shift keyed demodulator performance in the presence of various types of undesired signals. It utilizes models of the underlying random processes to determine the probability of a bit error. The basic calculation involves integrating the probability distribution function of the internal receiver noise (assumed to be Gaussian) plus the undesired signal. When this integral cannot be solved analytically, a sample-function analysis is utilized. Results are given that compare the effects of various undesired signals (i.e., continuous-wave, MPSK, impulsive noise, and gated noise) to those of Gaussian noise.
