Abstract
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 -stable (S S) distribution. Tradition- ally, this is a dicult problem since the analytical expression for the probability density function of a general S S distri- bution remains unknown. In order to tackle this diculty, 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 analytical results. The simulation results show that our proposed BER expressions are valid in the whole geometric signal-noise- ratio (GSNR)ranges, thus outperformingthe previous results valid only at high GSNR values.
