Abstract
In an embodiment, a system for multi-band predistortion has a predistortion actuator applying a first and a further adjustable distortion to a first band input and at least one further band input, respectively, based on the first band input and at the least one further band input to provide a first band output and a second band output, respectively. The predistortion actuator drives an output port configured to be coupled to an amplifier. The system further has a processor coupled to an evaluation input, which is couplable to an output of the amplifier. A coefficient calculation block is coupled to a processor output, the first band input, and the at least one further band input. The coefficient calculation block calculates first and the further adjustable distortion coefficients based on the first band input, the at least one further band input and the processor output.
