Method and system for calibrating a transceiver array

摘要

A system and method for compensating phase differences between multiple local oscillators and group delay differences between multiple transceivers. The system may include; an antenna array; a plurality of transceivers connected to said antennas and operatively associated each with a local oscillator (LO), wherein at least some of the transceivers do not share a common LO, and wherein at least some of the LOs are using a common reference oscillator; a common digital beamformer circuit connected to the transceivers; a baseband processor configured to operate the system at a specified communication scheme; and a calibration circuit and software modules configured to eliminate or reduce mismatches and phase deviations between the different transceivers, wherein the calibration circuit and software modules are incorporated in system such that the elimination or reduction of mismatches and phase deviations is non-interrupting with a continuous operation of the system at the specified communication scheme.

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.
