- Abstract
High power amplifier not only causes in-band intermodulation but also causes out-of-band harmonic distortion. For a wideband transmitter, harmonic distortion out of communication frequency can be restrained by a radio-frequency filter, but harmonic distortion in the communication frequency is difficult restrain. In this paper, we develop harmonic memory polynomial to model harmonic distortion and then propose a digital harmonic canceling algorithm based on direct learning structure -- nonlinear filtered-x affine projection algorithm (NFX-APA). Simulation and measurement results demonstrate that this novel digital canceling method can cancel harmonic effectively.
