Abstract

In this paper, we investigate the performance of the ARQ-aided downlink Time Switched Transmit Diversity (TSTD) in the WCDMA LCR-TDD system, when power ramping is applied. Proposed scheme ramps up the transmission power and then retransmits the data, when the receiver sends the response signal (ACK or NACK signal) to the transmitter and the response signal is NACK signal. Simulation results demonstrate that the proposed scheme yields about 0.7dB performance gain in terms of average Eb/N0, compared with the conventional ARQ-aided TSTD when a mobile speed is 3km/h and a frame error rate (FER) is 1%, respectively. In addition, 2.5% of throughput gain is achieved when the average Eb/N0 is equal to 0dB.
