Bit error rate of MRC receiver for BPSK signals in the presence of G fading

The performances of Maximal Ratio Combining (MRC) receivers in the presence of G fading over L independent diversity reception paths are presented in this paper. Coherent Binary Phase Shift Keying (BPSK) modulation is applied. For the bit error rate (BER) determination, the approach with moment generating function (MGF) and alternative representation of Gaussian Q-function are used. The bit error rate values are numerically calculated for different number of branches, then graphically represented for appropriate distribution factors values and finally compared and discussed.
