Abstract
Provided is a low-complexity transmit/receive antenna selection method for Multi-Input Multi-Output (MIMO) systems. The method includes the steps of generating a gain matrix of receive channel, calculating norm values of channel gains for each row (receive antennas) and column (transmit antennas) of the generated gain matrix of the receive channel, selecting an antenna with the maximum norm value among the calculated norm values of channel gains, and repeatedly performing the process of alternately selecting transmit and receive antennas having the maximum channel gain value among the channel gain values of the selected antenna until a required number of antennas is all selected.
