Abstract

In this paper, multiple-input multiple-output (MIMO) systems employing both transmit and receive antenna selection (TAS/RAS) are examined for independent and identically distributed (i.i.d.) flat Nakagami-m fading channels. Exact bit error rate (BER) expression for binary phase shift keying (BPSK) and binary frequency shift keying (BFSK) modulations are derived by using the moment generating function (MGF)-based analysis method. In the analysis, the transmit-receive link that maximizes the instantaneous received signal-to-noise ratio (SNR) is selected for transmission and reception. Exact BER results for different numbers of transmit and receive antennas are validated by Monte Carlo simulations. Also, upper bounds are obtained in order to show that the investigated systems achieve full diversity orders at high SNRs.
