Multiple-Input Multiple-Output (MIMO) systems play a great role in improving communication in wireless systems. But an increase in the number of antennas used in a communication system results in increased system complexity. To address this drawback associated with MIMO systems the authors propose the use of a transmit antenna selective MIMO system. In this the best performing transmit antenna is selected from all the available antennas for communication. The Signal-to-Noise Ratio (SNR) performance of the proposed system is studied as the number of antennas used in the system is increased. In studying the SNR performance, Maximal-Ratio-Combining (MRC) is used as the optimal combining technique at the receiver end.
