In this paper, the error performance of the Alamouti scheme with transmit antenna selection is investigated in the context of imperfect subset selection. The asymptotic bit error performance is derived for binary phase-shift keying (BPSK) modulation in flat Rayleigh fading channels. It is shown that the transmit diversity order is equal to the larger ordinal number of the antenna within the selected antenna subset, while the smaller ordinal number only determines horizontal location of the error performance curve without an impact on asymptotic diversity order. Simulation results are provided to substantiate the theoretical analysis.
