Analysis of Fm Signals Affected by Coloured Multiplicative Noise Using the Wigner-Ville Trispectrum

Abstract

The problem of analysing FM signals affected by white multiplicative noise was originally considered in [f]. In this paper we study a more realistic case of coloured multiplicative noise, and show how the degree of Doppler spread aflects the performance of the WignerVille trispectrum versus the traditional method, such as the WignerVille spectrum (WVS).
