Abstract:
A signal processing system and method, and an apparatus are provided. A phase recovery apparatus may be used to: receive a feedback signal fed back by an information iteration apparatus, perform, based on the feedback signal, phase recovery on a signal output by an equalizer, and output a phase-recovered signal to a post filtering apparatus, so that the post filtering apparatus performs noise filtering on the phase-recovered signal, and outputs a noise-filtered signal to the information iteration apparatus. To be specific, the phase recovery may be performed, based on the signal fed back by the information iteration apparatus, on the signal output by the equalizer. Because output of the information iteration apparatus is more accurate in determining the signal, precision of the phase recovery can be improved, cycle skipping is reduced, and input signal quality of the post filtering apparatus is improved.

Claim (Index 28):
The apparatus according to  claim 27 , wherein the phase recovery circuit is configured to:\n extract, based on the received feedback signal, a phase offset of the signal output by the equalizer; calculate an average value of the phase offset to obtain phase offset data; and perform, based on the phase offset data, the phase recovery on the signal output by the equalizer.
