An iterative technique of time- and frequency-domain clipping for reducing PAPR of OFDM signals

초록

In this paper, we propose a novel peak-to-average power ratio (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 error vector magnitude (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 constellarion errors. © 2007 IEEE.
