Abstract--This correspondence studies antenna selection for wireless
communications systems that employ multiple transmit and receive
antennas. We assume that 1) the channel is characterized by quasi-static
Rayleigh flat fading, and the subchannels fade independently, 2) the
channel state information (CSI) is exactly known at the receiver, 3)
the selection is available only at the receiver, and it is based on the
instantaneous signal-to-noise ratio (SNR) at each receive antenna, and 4)
space­time codes are used at the transmitter. We analyze the performance
of such systems by deriving explicit upper bounds on the pairwise error
probability (PEP). This performance analysis shows that 1) by selecting
the set of antennas that observe the largest instantaneous SNR, one can
achieve the same diversity gain as the one obtained by using all the
receive antennas, provided that the underlying space­time code has full
