Abstract:
A phase recovery device includes a phase recovery module and a residual phase recovery module. The phase recovery module performs a first-stage phase recovery on a received signal to generate a first phase recovered signal. The residual phase recovery module performs a second-stage phase recovery on the first phase-recovered signal to generate a second phase recovered signal.

Claim (Index 9):
The phase recovery device according to  claim 1 , wherein the received signal comprises a plurality of data signals and a plurality of pilot signals, and the phase recovery module comprises:\n a phase estimation module, comprising:\n a pilot phase estimating unit, calculating a plurality of pilot phase errors based on the plurality of pilot signals; \n a weighting unit, calculating a plurality of weightings corresponding to the plurality of pilot phase errors; and \n a combining unit, calculating a plurality of phase errors corresponding to the plurality of data signals according to the plurality of pilot phase errors and the plurality of weightings, wherein the plurality of phase errors are a linear combinations of the plurality of pilot phase errors; and \n a phase compensation module, compensating phases of the plurality of data signals according to the plurality of phase errors.
