Abstract:
A phase detector includes a decimator to decimate a digitized in-phase signal and a digitized quadrature signal to N times a symbol rate, where N is an integer greater than one. A burst detector to detect bursts in an output of the decimator. A carrier offset block to determine an offset angle based on an output of the burst detector. A rotator to generate a rotated signal by rotating the output of the decimator based on the offset angle determined by the carrier offset block. An equalizer to perform coherent demodulation of the rotated signal.
