In this paper, the performances of the Switch and Stay Combining/Maximal Ratio Combining (SSC/MRC) combiner output signal at two time instants is determined. The SSC and MRC combiners with two branches are considered. The presence of the log-normal fading at the input is observed. The probability density function (PDF) at the output of the combiner is obtained. Bit error rate (BER) for the special case of the binary phase swift keying (BPSK) modulation is derived. The results are shown graphically to emphasize better performances of the SSC/MRC combiner with regard to classical SSC and MRC combiners at one time instant.
