Enhanced beam selection for multi-user mm-wave massive MIMO systems

In millimetre wave (mm-wave) communications, hybrid precoding is preferred which uses much less number of RF chains compared with the number of antenna elements. The conventional method selects the beamforming vectors at base station (BS) and the combining vectors at user equipments (UEs) to maximise the received signal power. However, in some specific scenarios, when UEs have strong and highly co...
