In this paper, multi-antenna systems employing both single transmit and single receive antenna selection (single TAS/single RAS) are examined for independent and identically distributed (i.i.d.) flat Nakagami-m fading channels. In this joint selection scheme, signal transmission and reception is performed over a single communication link with the highest signal-to-noise ratio (SNR). Exact bit/symbol error rate expressions for binary modulation, M-ary phase shift keying and square M-ary quadrature amplitude modulation signals are derived by using the moment generating function based analysis method. Also, upper bounds are obtained in order to show that the investigated systems achieve full diversity orders at high SNRs. Besides, outage probability analysis is carried out for examining system capacity. Analytical results are validated by simulations.
