Abstract :
We investigate the error performance of a wireless communication system employing transmit-receive diversity in nonselective Rayleigh fading channels using a pilot-symbol-assisted-modulation (PSAM) technique. We first derive the optimum receive weight vector using the maximum likelihood detection principle, and then the optimum transmit weight vector based on minimization of the error probability. Both sets of weights are optimal in the presence of imperfect channel estimation. New bit error probability results for BPSK and QPSK are presented and the effects of various parameters in the PSAM system investigated.
