Abstract :
In this paper, the error performance of an uncoded multiple-input-multiple-output (MIMO) scheme combining single transmit antenna selection and receiver maximal-ratio combining (the TAS/MRC scheme) is investigated for flat Nakagami-m fading channels with binary phase-shift keying (BPSK) modulation. The asymptotic bit error rate (BER) expression is derived, which indicates a diversity order equal to the product of the m parameter, the number of transmit antennas and the number of receive antennas. The exact BER expression is also obtained as an infinite series, which converges for reasonably large signal-to-noise ratios (SNRs). The theoretic analysis is verified by simulation
