An Iterative Technique of Time-and Frequency-Domain Clipping for Reducing PAPR of OFDM Signals

OFDM 신호의 PAPR 감소를 위한 시간 및 주파수 영역 클리핑의 반복

In this paper, we propose a novel PAPR reduction scheme, which requires no change of a receiver structure or no additional information transmission. The approach we employed is clipping in the time and frequency domains within EVM, which is a suboptimal method with lower computational complexity compared to the optimal method. The simulation results demonstrated that the proposed method is more effective at lower modulation levels with larger constellation errors.
