Abstract

Analyzes the performance of a simple open loop transmit diversity (TD) scheme proposed by the authors for wideband CDMA systems under Rician multipath fading channels. In particular, the probability density function (pdf) of the output signal-to-noise ratio (SNR) and the uncoded bit error rate (BER) are derived. Numerical results show that the scheme with low complexity outperforms open loop space-time transmit diversity (STTD), and achieves a close performance to ideal closed loop transmit adaptive array (TxAA) in typical Rician multipath fading channels.
