Robust Receivers for FH-SS Signals in Channel with Additive Cauchy-Gaussian Mixture Noise

Abstract

This research is devoted to an analysis of a data transmission systems with Frequency Hopping-Spread Spectrum working in a presence of a mixture Cauchy-Gaussian noise. We consider coherent and non-coherent reception of such signals and four decision-making algorithms: correlation receiver, correlation receiver with a preliminary threshold, algorithm based on a binary quantization and algorithm based on a median statistic. As a result of the comparative analysis we figure out areas of applicability for the considered receivers and their dependency on distortion parameters.
