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 5):
The phase recovery device according to  claim 3 , wherein the characteristics unit comprises:\n a matrix unit, generating a covariance matrix corresponding to the phase error average vector; a decomposing unit, performing a decomposition operation on the covariance matrix to generate a plurality of eigenvectors and a plurality of eigenvalues of the covariance matrix; a selecting unit, selecting at least one eigenvalue from the plurality of eigenvalues, and selecting at least one eigenvector from the plurality of eigenvectors as the at least one eigenbasis, wherein the at least one eigenvector corresponds to the at least one eigenvalue; and a gain unit, calculating the at least eigengain according to the at least one eigenvalue.
