Abstract: Performance analysis of an L-branch Equal Gain Combining (EGC) receiver with phase estimation error and asynchronous Co-Channel Interference (CCI) over correlated Nakagami-m fading channel is presented. Both the desired and interfering signals are assumed to be Nakagami-m distributed. The output Signal to Noise Ratio (SINR) of the EGC combiner is derived. Closed form expression for the n-th moment of the output SINR is derived. Using the n-th moment expression, Average Bit Error Probability (ABEP) for Binary Phase Shift Keying (BPSK) modulation is derived using Moment Generating Function (MGF) and Padé approximation method. Numerical and simulation results of ABEP for various desired and interfering signal parameters are obtained. ABEP results for various degrees of phase errors are also obtained. The results for special cases are verified with the available results.
