Abstract

Owing to the high cost of radio frequency (RF) chains and power consumption of broadband signals, it is suitable to include both analogue and digital processing for millimetre wave (mmWave) beamforming. In this study, hybrid beamforming (HBF) schemes are considered for multi-user downlink mmWave systems. RF beamforming schemes are proposed for HBF transmission with perfect channel state information at transmitter (CSIT) and limited feedback information in the multi-user mmWave channel. Simulation results show that proposed HBF schemes enhance sum rate performance than conventional HBF schemes in both cases of perfect CSIT and limited feedback.
