"More spectrum-efficient techniques are required for wireless communications with a limited amount of bandwidth. Space division multiplexing (SDM) is one of the most promising techniques for achieving more efficient bandwidth utilisation, since it enables the transmission rate over multiple-input multiple-output chennels to be increased by using multiple antennas on both the transmitter and receiver sides," scientists writing in the journal Iet Microwaves Antennas & Propagation report.
"Recently, since the cost of RF transmitters is much higher than that of antennas, there is a growing interest in techniques that use a larger number of antennas than RF transmitters....
