Abstract :
We consider the performance analysis of generalized selection combining (GSC) for BPSK signals in time-correlated Rayleigh fading channels. For the coherent detection of BPSK signals, we employ pilot symbol aided modulation (PSAM) to provide channel side information (CSI) and the optimum GSC follows the maximal signal to noise ratio (SNR) criterion. To analyze the bit-error-rate (BER) of GSC for BPSK signals, we propose a novel method based on the Monte-Carlo integration technique to circumvent the high computational complexity occurred in the evaluation of analytical BER expression.
