1. A digital compensator comprising:

  • at least one fixed, discrete-time (DT), linear time invariant (LTI) filter that provides an output signal z[n] and that is configured based on the known non-linear aspects of an analog receiver to a continuous time input signal x(t);

    a reduced-complexity, discrete-time, nonlinear compensator that follows the fixed, discrete-time (DT), linear time invariant (LTI) filter to receive the output signal z[n] and provides a compensated output signal u[n];

    wherein the digital compensator is configured to substantially reduce the one or more nonlinear distortion components in a sampled digital output signal of the analog receiver y[n] to provide the output signal u[n] achieving a receiver linearity requirement for the combination of the analog receiver and the digital compensator.
