Abstract:
1. A method, comprising: obtaining calibration data for a plurality of signal processing paths each associated with a transmission device from a plurality of transmission devices; determining a plurality of calibration weights from the calibration data; calculating a calibration variance between the plurality of calibration weights and determining if the calibration variance is below a calibration variance threshold; calculating a phase variation and a magnitude variation from the calibration data for each signal processing path from the plurality of signal processing paths; determining if the phase variation is below a phase variation threshold and if the magnitude variation is below a magnitude variation threshold for each signal processing path from of the plurality of signal processing paths; and applying a calibration weight from the plurality of calibration weights to a signal processing path from the plurality of signal processing paths when the calibration variance is below the calibration variance threshold, the phase variation associated with that signal processing path is below the phase variation threshold and the magnitude variation associated with that signal processing path is below the magnitude variation threshold.
