Abstract

In this work, bit/symbol error rate (BER/SER) performances of multiple-input multiple-output (MIMO) systems that employ Alamouti coded transmission with transmit antenna selection (TAS) are examined for independent but non-identical flat Nakagami-m fading channels. Exact BER/SER expressions are derived by using the moment generating function (MGF)-based analysis method for binary phase shift keying (BPSK), binary frequency shift keying (BFSK), M-ary phase shift keying (M-PSK) and M-ary quadrature amplitude modulation (M-QAM) signals. Also, upper bound expressions have been obtained in order to examine the asymptotic diversity order of TAS/Alamouti scheme. Monte Carlo simulations have validated the theoretical SER performance results derived for different numbers of transmit and receive antennas.
