This paper discusses the performance analysis of multi-antennas systems with receive antenna selection over quasistatic fading channels. In performing the analysis with antenna selection, the selection criterion adopted is based on selecting best Nr antennas out of the available NR3 receive antennas such that the instantaneous signal-to-noise ratio (SNR) at the receiver is maximized. It is assumed that the total number of transmit antennas, NT =2, are equal to or greater than the total number of receive antennas. From the analysis it is shown that the resulting diversity order with antenna selection is maintained as that of full complexity system, however the coding gain deteriorates in proportion with reduced number of receive antennas. The results obtained with antenna selection with NR =2 and N R3 =3 multi-antenna systems are compared. © 2008 IEEE.
