Detection of MDPSK in Fading Channels using Gaussian Particle Filter

Abstract

We propose Gaussian particle filtering approach for solving the problem of corrupting the MDPSK signals by fading as well as noise. Particle filtering is a powerful tool for non linear problems but it faces sampling degeneration problem which leads to re‐sampling process. Gaussian Particle Filtering doesn’t need re‐sampling process because it approximates the posterior distribution as Gaussian.GPF is preferable than PF for fading channels.
