Abstract

An exact expression for the output autocorrelation function of an FM discriminator is derived when the input of the FM discriminator is an FM signal, cochannel interference and Gaussian noise. The modulating baseband signals for the FM signal and the cochannel interference are assumed FDM signals whose statistics are modeled by a stationary Gaussian random process. The interaction among signal, interference and noise are determined by which the NPR (noise-power-ratio) can be calculated
