Abstract:
1. A system comprising: an antenna array comprising antennas; a plurality of transceivers connected to said antennas and each transceiver operatively associated with a local oscillator (LO), wherein at least some of the transceivers are not associated with the same LO, and wherein at least some of the LOs use a common reference oscillator; a common digital beamformer circuit connected to said transceivers; a baseband processor configured to operate the transceivers and beamformer circuit at a specified communication scheme; and a calibration circuit, wherein said calibration circuit and said baseband processor executing software modules are configured to reduce mismatches and phase deviations between the transceivers in a non-interrupting manner with a continuous operation of the system at the specified communication scheme.
