摘要

Signal clipping is known to be the simplest method to reduce the peak to average power ratio (PAPR) in OFDM systems. Clipping will introduce the clipping noise (CN) degrading system performance. Most clipping noise mitigation algorithms require to know the clipping ratio (CR) in the receiver; however, this may not be possible for all applications. We propose a new clipping ratio estimation method which can be applied to pilot-tone-based OFDM systems. Simulation results show that the proposed algorithm can estimate CR accurately and clipping noise can be effectively mitigated.
