Average Bit Error Rate Analysis of Selection Combining over Beaulieu-Xie Fading Model

Abstract

This research work investigates the error performance of Beaulieu-Xie (BX) fading channel with L-branch selection combining (SC) technique. First, the cumulative distribution function (CDF) of BX fading is derived by employing the SC technique. The analytical expression for the probability density function (PDF) is derived from the obtained CDF. By using the derived PDF, other performance metrics such as outage probability (OP), average bit error rate (ABER) of different modulation schemes are obtained. To study the effect of fading parameters and diversity branches on the ABER, the numerical results are plotted and verified by Monte Carlo simulation.
