Claim One:
1. A digital compensator for a signal chain comprising at least one analog amplification element, the digital compensator comprising: an input for receiving a desired signal; an output for providing a compensated signal; a storage for a plurality of coefficients; and a signal processor coupled to the input and to the output for processing a desired signal to produce the compensated signal according to the plurality of coefficients; wherein the signal processor comprises a basis formation stage coupled to a basis combination stage; the basis formation stage includes a plurality of basis formation elements, each configured to produce a basis signal that depends on the desired signal provided to the input; at least some of the basis formation elements each includes a non-linear element configured to produce a non-linear transformation of the desired signal, and a filter configured to produce a time filtering of the non-linear transformation; the basis combination stage is configured to accept the plurality of basis signals from the basis formation elements, and to produce a combined signal from said basis signal according to the plurality of coefficients; and the digital compensator is configured to provide the compensated signal at the output according to the combined signal produced by the basis combination stage.
