Patent ID: 8203483

Claim:
A multi-antenna transceiver for beamforming, the multi-antenna transceiver comprising: a plurality of transmit antennas; a corresponding plurality of transmit processors, wherein each transmit processor is electrically coupled with a corresponding transmit antenna, wherein each transmit processor is configured to: receive bits to be transmitted, receive a transmit time offset, receive a transmit phase shift, and generate a modulated waveform based on the received bits, the transmit time offset and the transmit phase shift, wherein the modulated waveform is coupled to the corresponding transmit antenna; a plurality of receive antennas configured to receive a signal, a plurality of receive processors, wherein each individual receive processor is electrically coupled with a corresponding receive antenna, and wherein each receive processor is configured to demodulate the signal to generate baseband samples, wherein the demodulation is at least partially based on a receive time offset and a receive phase shift; and a central processing unit configured to generate: a plurality of receive time offsets and receive phase shifts for the plurality of receive processors and a plurality of transmit time offsets and transmit phase shifts for the plurality of transmit processors, and wherein: the plurality of receive time offsets include the receive time offset, the plurality of receive phase shifts include the receive phase shift, the plurality of transmit time offsets include the transmit time offset, the plurality of transmit phase shifts include the transmit phase shift, the plurality of receive time offsets and receive phase shifts being configured to beamform with the plurality of receive antennas and/or receive processors, and the plurality of transmit time offsets and transmit phase shifts being configured to beamform with the plurality of transmit antennas and/or transmit processors.
