Abstract

In this paper, we investigate the performance of ARQ-aided downlink Time Switched Transmit Diversity (TSTD) in the WCDMA LCR-TDD system. The proposed TSTD system employs the ARQ scheme in which the receiver sends the acknowledgement signal (ACK or NACK signal) to the transmitter in order to predict the channel condition. Simulation results demonstrate that the proposed TSTD scheme yields about 4.5dB gain in terms of EbINO, compared with the conventional TSTD when the mobile speed is 3kmlh and a frame error rate is 1%. In addition, the throughput gain of 6% is shown when Eb1N0=7dB.
