Communication methods and systems for nonlinear multi-user environments

A system comprising:

• an electronic receiver configured to communicate with a first communication partner and a second communication partner, wherein said receiver comprises:
• nonlinear distortion modeling circuitry operable to:
• determine a first set of nonlinear distortion model parameter values that model nonlinear distortion present in signals from said first communication partner;
• and
• determine a second set of nonlinear distortion model parameter values that model nonlinear distortion present in signals from said second communication partner;
• and
• nonlinear distortion compensation circuitry operable to:
• use said first set of nonlinear distortion model parameter values for processing of signals received from said first communication partner;
• and
• use said second set of nonlinear distortion model parameter values for processing of signals received from said second communication partner.

A method comprising:

• in an electronic receiver:
• determining, by a nonlinear distortion modeling circuit of said electronic receiver, a plurality of sets of nonlinear distortion model parameter values, each of said sets of nonlinear distortion model parameter values representing nonlinear distortion experienced by signals received by said electronic receiver from a respective one a plurality of communication partners;
• and
• processing, by a nonlinear distortion compensation circuit of said electronic receiver, signals from said plurality of communication partners using said sets of nonlinear distortion model parameter values.
