Analysis of partially coherent PSK systems in wireless channels with equal-gain combining

A new method has been developed to analyze the performance of partially coherent PSK systems in wireless channels with equal-gain combining. We evaluate the detection loss suffered and the phase precision required for the carrier recovery for different error rates and with different degradations when BPSK and QPSK systems are used in the wireless channels. Generalized fading conditions including Rayleigh, Ricean, and Nakagami-m are taken into account.
