Abstract

We investigate the error performance of the Alamouti scheme with transmit antenna selection. The exact bit error rate (BER) is derived for binary phase-shift keying (BPSK) in flat Rayleigh fading channels. The analysis reveals that this scheme achieves a full diversity order at high SNRs, as if all the transmit antennas were used. Simulation results are provided to substantiate the analysis. It is shown that compared with conventional space-time block codes (STBCs), this scheme incurs much less SNR loss inherent to the transmit-diversity system. Therefore, the Alamouti scheme with transmit antenna selection provides a new general approach to the design of MIMO systems for high-data-rate downlink transmission with a high diversity order.
