Abstract:
A transceiver for receiving and transmitting signals, said transceiver comprising:an array of antennas, each of the antennas being randomly positioned relative to each other, each of the antennas identifying a separate channel of the transceiver where one of the channels is a reference channel, each channel receiving and transmitting signals on a common carrier frequency including the same data; a code generation system, said code generation system generating a unique calibration signal for each channel, each channel transmitting its calibration signal and receiving the calibration signals from all of the channels; an alignment error system, said alignment error system generating an alignment error signal that identifies an alignment error between the calibration signal transmitted by each channel and the calibration signal transmitted by the reference channel; a phase error determination system, said phase error determination system determining a phase error signal that is the difference between the phase of the carrier signal transmitted by each channel and the phase of the carrier signal transmitted by the reference channel; and a correction system, said correction system generating a time correction for each channel that aligns the calibration signal transmitted by each channel with the calibration signal transmitted by the reference channel and generating a phase correction signal that aligns the phase of the carrier signal transmitted by each channel and the phase of the carrier signal transmitted by the reference channel.
