A signal is predistorted by producing a first set of sample values using a first predistortion technique, producing a second set of sample values using a second predistortion technique different than the first predistortion technique, and combining the first and second sets of sample values to produce a predistorted signal. At least one of the first and second predistortion techniques produce the corresponding set of sample values based at least in part on a plurality of past time spaced input samples relative to a current time spaced input sample. By way of example, the first predistortion technique may be configured to produce sample output values each of which is dependent on one of a plurality of time spaced input samples and independent of any other time spaced input sample, and the second predistortion technique may be configured to produce sample output values each of which is dependent on (i) at least one of a plurality of past time spaced input samples and (ii) a current time spaced input sample, and independent of any other time spaced input sample.
