Abstract
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.
Claims19
1-20. (canceled)
A method comprising:
- in an electronic receiver:
- receiving a signal;
- converting said received to a symbol-domain signal;
- generating an estimate of symbols transmitted to generate said received signal;
- and
- generating an error signal indicative of an error in said generated estimate of said symbols, wherein said generating said error signal comprises nonlinearly distorting said estimate of said symbols.
The method of claim 278, wherein said nonlinearity modeling circuit models a nonlinearity of a transmitter from which said received signal was received.
A system comprising:
- circuitry for use in an electronic receiver, the circuitry comprising a nonlinearity modeling circuit and being operable to:
- receive a signal;
- convert said received signal to a symbol-domain signal;
- generate an estimate of symbols transmitted to generate said received signal;
- and
- generate an error signal indicative of an error in said generated estimate of said symbols, wherein said generation of said error signal comprises nonlinearly distorting of said estimate of said symbols via said nonlinearity modeling circuit.
The system of claim 38, wherein said nonlinearity modeling circuit models a nonlinearity of a transmitter from which said received partial-response-domain signal was received.
The system of claim 38, wherein said nonlinearity modeling circuit models a nonlinearity of a front-end of said electronic receiver.
