Abstract

In this paper, the performance of switch and stay combing (SSC) diversity receivers operating over correlated Ricean fading channels, is studied. By representing the bivariate Ricean distribution as infinite series the probability density function (PDF) of the SSC output signal-to-noise ratio (SNR) has been derived. Capitalizing on this PDF the moments of the output SNR and the corresponding cumulative distribution function (CDF) have been also obtained. Furthermore, an analytical expression for the moments generating function (MGF) is derived and by employing the MGF-based approach the average bit error probability (ABEP) for several modulation schemes is studied. Finally, various performance evaluation results, such as average output SNR (ASNR), amount of fading (AoF), outage probability (Pout) and ABEP are presented.
