Performance of a nonlinear FHDPSK spreadspectrum receiver with multiple narrowband interfering signals
Abstract
An analysis of the effect of multiple narrowband interfering signals on the probability of error in a frequencyhopped differential phase shift keyed (FHDPSK) spreadspectrum communication system with a nonlinear receiver is given. In this analysis it is assumed that the sum of the outputs from an nsubchannel receiver is a Gaussian random variable. Subject to this assumption, numerical evaluations of the probability of error for both nonfading and Rayleigh fading channels are presented and compared with those of a linear receiver. The results indicate that the performance of a nonlinear receiver is better than that of a linear receiver for any signaltointerference ratio.
