摘要：

The design of the broadband transmitter faces the challenge of canceling harmonic distortion in the communication frequency band. Here we improve the digital predistortion (DPD) to propose a digital harmonic canceling algorithm based on direct learning structure-a reverse function predistorter based on IIR and FIR filter structure, which have less computational complexity and achieve better effect compared with the nonlinear adaptive filter. Experimental results verify the effectiveness of this canceling algorithm.
