This paper presents a study on the performance of Maximal Ratio Combiner (MRC) diversity scheme over frequency-nonselective, slowly fading Nakagami-m multipath fading channel. Expressions for average bit error probability (BEP) during system outage are derived for M-ary Phase Shift Keying (PSK) coherent modulation scheme using the Chernoff bound and, simple and very tight bounds on Gaussian Q-function given by [1]. Expressions obtained are numerically evaluated to study the effect of fading parameter and diversity order.
