Performance of Differentially Detected DPSK over the Nonselective Rayleigh Fading Channels with Maximal Ratio Combining and Multiple asynchronous cochannel Interferers

摘要

In this paper we investigate the performance of differentially detected differential phase shift keying with post-detection maximal ratio combining, in nonselective Rayleigh fading channels with multiple asynchronous cochannel interferers. Exact bit error probability results for binary DPSK and quaternary DPSK are derived. More specifically, we analytically study the effects of symbol timing offsets between the interfering signals and the desired signal on the error performance.
