Performance Analysis of Diversity Combining over Rayleigh Fading Channels with Impulsive Noise

Anotace: This paper investigates the performance analysis of diversity combining over flat fading channels subject to additive impulsive noise. Specifically, the impulsive noise follows the symmetric α-stable (SαS) distribution. Tradi- tionally, this is a difficult problem since the analytical ex- pression for the probability density function of a general SαS distribution remains unknown. In order to tackle this diffi- culty, we adopt Fourier power transform to obtain an exact bit error rate (BER) expression for the Genie-aided receiver as well as a BER upper bound for the conventional linear matched filter receiver, without taking any approximation. Monte-Carlo simulations are performed to validate our ana- lytical results. The simulation results show that our proposed BER expressions are valid in the whole geometric signal- noise-ratio (GSNR) ranges, thus outperforming the previous results valid only at high GSNR values.
