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 18):
The system according to  claim 16 , wherein:\n the sequence detection information is at least one of sequence detection soft value information or sequence detection hard decision information; and the error detection information is at least one of error detection soft value information or error detection hard decision information, wherein soft value information is at least one of information reflecting a probability that sequence symbols in the signal are a specified symbol, or information reflecting a ratio of probabilities that the sequence symbols in the signal are different specified symbols, and hard decision information is information reflecting specific values of the sequence symbols in the signal.
