Abstract

This paper considers the bit error rate (BER) performance of the 3GPP WCDMA-FDD system with space-time transmit diversity in the indoor environments by employing a resolution-reduced maximum ratio combing (RR-MRC) RAKE receiver. An average uncoded BER lower bound is used for the BER performance analysis, which is based on a proper complex Gaussian (PCG) multichannel assumption without inter-symbol interference (ISI). Numerical results show that substantial diversity diversity gain can still be obtained with the suboptimal RR-MRC receiver even in a mixed-mode fading multipath channel with the rms delay spread around 50 nanoseconds.
