Signal reception using non-linearity-compensated, partial response feedback

摘要

A receiver may receive a signal that was generated by passage of symbols through a non-linear circuit. An equalizer of the receiver may equalize the received signal based on a first non-linearity compensated, inter-symbol correlated (ISC) feedback signal to generate an equalized signal. The receiver may correct a phase error of the equalized signal to generate a phase-corrected equalized signal. The phase correction may be based on a second, non-linearity compensated, inter-symbol correlated (ISC) feedback signal.

1. A method comprising:
in an electronic receiver:
receiving a partial-response-domain signal;converting said received partial-response-domain signal to a symbol-domain signal, said converting comprising equalizing said received partial-response-domain signal to generate an equalized partial-response-domain signal;converting said symbol-domain signal to a first partial-response-domain feedback signal;configuring said electronic receiver based on said first partial-response-domain feedback signal;generating an error signal based on said first partial-response-domain feedback signal and said equalized partial-response-domain signal, said generating comprising, calculating a Euclidean distance between said first partial-response-domain feedback signal and said equalized partial-response-domain signal.
