Performance of Digital Communication Receivers Operating in the Presence of White Gaussian Nonstationary Noise

摘要

The problem of evaluating the performance of digital communication receivers operating in the presence of additive white Gaussian noise (AWGN) and nonstationary AWGN is addressed. A specific model for the nonstationary AWGN is proposed and the corresponding performance of conditional digital communication receivers is derived. Additionally, receivers that are optimum (in minimum probability of error sense) for detecting binary signals in the presence of noise and the nonstationary interference modeled is derived and its performance evaluated. Several examples involving Phase Reversal Keyed modulation and frequency Shift keyed modulation for various forms of the nonstationary interference are worked out.
