ABSTRACT:
A cascaded distortion compensation arrangement is disclosed which utilizes a plurality of pre-distortion components disposed in a series arrangement at the input to the transmitter and a plurality of post-distortion components disposed in a series arrangement at the output of the receiver. The various components may be modified, added and/or deleted to provide an arrangement suitable for the particular system.
