Many-Antenna Full-Duplex with Fully Digital and Hybrid Beamforming Radios
2021 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)（2021）
摘要
Next generation wireless systems are expected to use a very large number of antennas at base stations (BSs). For example, the 3GPP has already included support for up to 128 antenna BSs for sub-6 GHz cellular systems in its standard specifications. The traditional approach to build many-antenna BSs is to connect each antenna element to a separate Tx-Rx RF chain (an architecture referred to as foll...
