General Expression for BER with MRC Reception over Rayleigh Fading Paths

Vo Nguyen Quoc Bao, Hyung-Yun Kong

Open publisher page 0 citations

Abstract

This paper provides a general and compact expression for the probability density function (pdf) and the moment-generating function (MGF) of the maximal ratio combiner output over Rayleigh fading channels. It is then used to derive closed form expression bit error rate (BER) for M-PSK, M-PAM and M-QAM, respectively. A variety of simulations is performed and shows that they match exactly with analytic ones.
