Abstract:
Beamforming system and method which includes an inverse beamformer with first ports and second ports, a beamformer with beam ports and antenna ports, and antennas. The inverse beamformer may receive transmit signals provided to first ports, generates intermediate signals based on the transmit signals, and output the intermediate signals from the second ports. The beamformer's beam ports may couple to the second ports and the antenna ports, and may receive the intermediate signals at the beam ports, generate antenna signals based on the intermediate signals, and output the antenna signals at the antenna ports. The antennas may each receive an antenna signal from an antenna port, and transmit the antenna signal into space. The inverse beamformer may generate the intermediate signals in a manner that is mathematically inverse to the beamformer's generation of the antenna signals so that the antenna signals approximate the transmit signals up to respective phase shifts.
