✦ Synopsis
The performance of the partially coherent equal gain combining receiver for binary phase-shift keying and quaternary phase-shift keying signals transmitted over the Weibull fading channels is analysed in this paper. The bit error rate (BER) degradations caused by simultaneous influences of incoherently combining and fading severity are determined. The numerical and simulation results show that stochastic phase error causes irreducible error floor. Efficient approximated closed-form expressions for BER floor are derived.
