Claim:
A method of compensating for distortion of an input signal by an electronic device that operates on the input signal to produce an output signal, said method comprising: computing a set of model coefficients for a two-dimensional lattice prediction model of an orthogonal basis function set from a set of input signal samples over a predetermined sampling interval, wherein the lattice prediction model represents orthogonal basis functions in the orthogonal basis function set as different combinations of fundamental basis functions; determining, from said set of model coefficients, a corresponding set of connection coefficients for combining fundamental basis function output signals from the fundamental basis functions to generate orthogonal basis function output signals; computing a set of fundamental basis function output signals from an input signal and the set of fundamental basis functions; applying the set of connection coefficients to the fundamental basis function output signals to produce a set of orthogonal basis function output signals; and combining the orthogonal basis function output signals to produce a predistorted input signal from the input signal.
