Approximation Error Analysis for Partially Coherent EGC Receiver under Nakagami-m Fading Channels

Abstract

We present the approximated bit error rate (BER) performance of a binary phase shift keying (BPSK) modulated equal-gain combining (EGC) diversity receiver with phase noise over independent and non-identical Nakagami fading branches. The approximated BER becomes accurate with phase-locked loop (PLL) gain, K = 20. Also, for special values of fading parameter, m, and branch number, L, we derived the closed form expression of the BER.
