Distributed beamforming system with user side beamforming processing

Abstract:

A distributed beamforming system including a platform terminal and a plurality of user terminals is disclosed. An individual user terminal includes a receiver configured to receive a plurality of individual wireless signals, where the plurality of individual wireless signals are transmitted by the platform terminal and are orthogonal with respect to one another. The individual user terminal also includes one or more frequency converters configured to transform each of the plurality of individual wireless signals to an intermediate frequency. The individual user terminal is configured to coherently combine the plurality of individual wireless signals together to form a beamformed signal.
