Abstract

This paper derives the average bit error probability (BEP) of the differential quaternary phase shift keying (DQPSK) with postdetection equal gain combining (EGC) diversity reception over arbitrarily correlated Nakagami-m and Rician fading channels. Our main contribution lies in presenting relatively simple BEP expressions, the error expressions are given in terms of a finite sum of a finite-range integral. The penalty in signal to noise ratio (SNR) due to arbitrarily correlated channel fading is investigated. It is observed that the performance degradation due to the correlation among the diversity branches in Rician fading channels is severer than that in Nakagami-m fading channels as a result of the presence of the specular component.
