Abstract :
The performance of transmit antenna selection is investigated. The exact closed-form expressions for the average BER and average SNR in MRT systems and EGT systems are proposed. The minimum number of increased transmit antennas sufficient to compensate the performance loss for using part of transmit antennas is analyzed. The validity of the performance analysis is demonstrated by computer simulation.
