Abstract:
Abstract In this correspondence, we develop a framework to analyze the symbol error probability (SEP) of downlink multiuser diversity (MUD) transmit antenna selection with orthogonal space-time block codes (TAS/OSTBC) over Rayleigh fading channels. Two excellent transmit antennas are chosen that maximize the received signal-to-noise level. Utilizing the moment generating function, a tight closed-form analytical expression of MUD order is derived in terms of SEP. The results shows that the MUD system can achieve a gain of diversity equal to the product of the number of users, number of transmit antennas and number of receive antennas.
