资源说明:This letter develops a framework to analyze the multiuser diversity (MUD) gain in multiple-input multiple-output (MIMO) transmit antenna selection with a maximal-ratio combining (TAS/MRC) system, through which the transmitter selects the optimal antenna out of the total transmit antennas based on the channel state information (CSI) feedbacks. Over a flat-fading Rayleigh channel, a tight analytical closed-form expression of the MUD gain in terms of outage probability is derived. The analytical re
