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 19):
The system according to  claim 18 , wherein\n the information iteration circuit comprises a sequence detection circuit and a forward error correction circuit; the sequence detection circuit is configured to:\n receive the error detection soft value information fed back by the forward error correction circuit; \n perform, based on the error detection soft value information, the sequence detection on the noise-filtered signal output by the post filtering circuit; \n output the sequence detection soft value information to the forward error correction circuit; \n use, as the feedback signal, the sequence detection soft value information or the sequence detection hard decision information that is obtained when the sequence detection is performed on the noise-filtered signal output by the post filtering circuit; and \n feed back the feedback signal to the phase recovery circuit; and \n the forward error correction circuit is configured to:\n perform error detection on the sequence detection soft value information output by the sequence detection circuit, to recover the original signal; and \n feed back the error detection soft value information to the sequence detection circuit.
