Hybrid Method of Tone-Injection and Clipping-and-Filtering for Suppressing Nonlinear Distortion of OFDM Signal

Abstract

In this paper, we propose hybrid methods of Tone-Injection (TI) and Clipping-and-Filtering (CF) for suppressing the non-linear distortion of OFDM. TI utilizes the genetic algorithm to search for an effective solution. The proposed methods are evaluated in terms of Peak-to-Average-Power Ratio (PAPR), Bit-Error-Rate (BER), and out-of-band radiation. The effectiveness of the proposed methods is demonstrated in the simulation.
