Patent ID: 8391809

Claim:
A system for multi-band predistortion comprising: a predistortion actuator, wherein the predistortion actuator applies a first adjustable distortion to a first band input based on the first band input and at least one further band input to provide a first band output, the predistortion actuator applies an at least one further adjustable distortion to the at least one further band based on the at least one further band input and the first band input to provide an at least one further band output, and the predistortion actuator is configured to drive an output port configured to be coupled to an amplifier; an output processor coupled to an evaluation input, the evaluation input couplable to an output of the amplifier; and a coefficient calculation block coupled to an output of the output processor, the first band input, and the at least one further band input, the coefficient calculation block calculating coefficients for the first adjustable distortion and the at least one further adjustable distortion based on the first band input, the at least one further band input and the output of the output processor.
