Abstract:
In a nonlinear signal filtering system, a signal having a series of signal samples is filtered. The signal samples are affected by interactions with adjacent signal samples and nonlinear distortions. The system contains a series of alternating linear system elements and nonlinear system elements that are used for mitigation of distortion resulting from the nonlinear distortions with memory effects. The linear system elements can scale each signal sample in the series of signal samples by scaling parameters and sums a plurality of consecutive scaled signal samples, and the nonlinear system elements can transform the output of the linear system elements according to instantaneous nonlinear functions.

Claim (Index 27):
A method for filtering a signal comprising:\n providing a signal comprising a series of signal samples, wherein a first signal sample in the series of signal samples is affected by an interaction with one or more consecutive signal samples adjacent to the first signal sample, and a value of each signal sample is subject to nonlinear distortions; filtering the signal through a first linear system element, wherein the first linear system element scales each signal sample by a scaling coefficient and sums a plurality of consecutive scaled signal samples; and filtering an output of the first linear system element using a first nonlinear system element, wherein the first nonlinear system element transforms the output of the first linear system element according to a multi-dimensional look-up-table; wherein the scaling coefficients in the first linear system element and the multi-dimensional look-up-table of the first nonlinear system element correct for the signal sample interactions and the nonlinear distortions in the value of each signal sample in the signal.
