Abstract:
1. A system comprising: an inverse beamformer including a first plurality of ports and a second plurality of ports, wherein the inverse beamformer is configured to: a beamformer including a plurality of beam ports and a plurality of antenna ports, wherein each of the beam ports is coupled to a respective one of the ports of the second plurality, wherein the beamformer is configured to: a plurality of antennas, wherein each of the antennas is configured to receive a respective one of the antenna signals from a respective one of the antenna ports and to transmit the antenna signal into space, wherein the inverse beamformer is configured to 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 respective transmit signals up to respective phase shifts.
