The Performances of Complex SSC/MRC Combiner in the Presence of Rayleigh Fading

Dragana Krstic, Petar Nikolic, Dragan Radenkovic


The probability density function (PDF) of dual-branch Switch and Stay/Maximal Ratio Combining (SSC/MRC) combiner output signal at two time instants in the presence of Rayleigh fading is determined in this paper. Afterwards, this PDF is used for calculation of the bit error rate (BER), outage probability (Pout) and amount of fading (AF) for complex SSC/MRC combiner for binary phase swift keying (BPSK) modulation, depending on some parameter values. Graphically presented results point out the gain of using this complex SSC/MRC combiner compared with classical MRC combiners and one channel receiver at one time instant. It can also be concluded that using of this complex SSC/MRC combiner is not economical in the case of strongly correlated signals.
