Abstract
The large peak to average power ratio (PAPR) is widely believed as one of the most critical problem for OFDM systems and a lot of methods have been proposed to reduce PAPR. When OFDM signal passes through a non-linear amplifier, the large PAPR may degrades the performance due to the clipping. In this paper, we show that the clipping noise and PAPR are weakly related when the clipping threshold is low where the impact of clipping is large. However,the popular PAPR reduction schemes are only effective when the threshold is high.
