Performance Evaluation of 44GHz Band Massive MIMO Based on Channel Measurement

5th generation mobile communication system using higher frequency band has gotten much attention, and massive-MIMO technologies have been expected to improve spectral efficiency dramatically. In order to reduce the complexity of massive-MIMO base station, the combination of analog beamforming (APAA: Active Phased Array Antenna) and digital MIMO signal processing for the multi-beam multiplexing is one of the promising approaches. In this paper, channel capacity evaluation with 44GHz-band APAA measurement results will be carried out and the possibility of large capacity transmission in LOS environment is shown. 44GHz band channel parameters - AoA, AoD, delay spread, etc. - will be shown and transmit performance results using cluster model are presented.
