A novel MIMO receiver using antenna selection and time-multiplexed single RF technique

A multiple-input-multiple-output (MIMO) receiver with reduced complexity has been introduced. The receiver selects the outputs of L antennas from N available antennas. Then; a single time-multiplexed RF front end down converts the signals of L antennas to the baseband. This implies that only one RF front-end may be used. It is shown by use of the analytical and simulation studies that a full diversity order can be achieved with this efficient receiver.
