Frequency component controllable digital predistortion of RF power amplifiers

In this paper, a novel frequency component controllable digital predistortion (DPD) for radio frequency (RF) power amplifiers (PAs) is proposed. The detailed analysis and experimental results demonstrate that the target band or frequency component to be linearized can be arbitrarily chosen according to user's demand by employing the proposed approach, which makes digital predistortion much more flexible in future wireless communication systems.
