Method for Radio Antenna Calibration Performance Measurement

摘要

Antenna Array, Massive MIMO, Radio Base Station, Radio Access Network, Antenna Calibration, Phase Error, Reciprocity, AAS, Beamtorming In current 4G and 5G radio access network (RAN), the massive MIMO or FD-MIMO technology is used to have enhanced performance on multiple areas e.g. cell coverage, throughput, spectrum usage etc. The massive number of antennas is key to support this technology. With wireless network on higher frequency or even millimeter-wave spectrum, the number of antennas would be increased up to hundreds.
