Abstract:
A cellular communication system comprising:a first transceiver at a base station having a first processor and a first directional antenna; a second transceiver on a mobile unit having a second processor and a second antenna; a locator on the mobile unit that determines a physical location of the second antenna; a spatially multiplexed communication link formed between the first and second transceivers, the link, including a wireless beam from the first antenna to the second antenna; and a first adaptive programmable beamformer circuit in the first transceiver that shapes the wireless beam to be directed between the first antenna and the second antenna, the first adaptive programmable beamformer circuit having a single integrated chip having a plurality of complex multipliers, a plurality of down conversion circuits and a plurality of finite impulse response (FIR) filters programmable with respect to a plurality of weights and a steering circuit that adjusts the plurality of weights to the programmable beamformer circuit.
