AIR-TO-GROUND (ATG) UPLINK SUBBAND BEAMFORMER WITH COMBINABLE SUBBANDS

摘要

Aspects of the present disclosure generally relate to techniques and apparatus that may help improve greatly reduce the implementation complexity of the ground station, and ground base-station user capacity by utilizing a subband beamformer for processing uplink signals received from aircraft at ground base stations, in an air-to-ground (ATG) system. The techniques presented herein may allow for dynamic subband allocation to different airborne devices with multi-user beamforming and subband combining.
