Abstract

The high peak to average power ratio in the cognitive NC-OFDM system causes the signal to fall into the nonlinear region of the linear amplifier, resulting in large distortion. Combining the advantages of partial transmission sequence algorithm and clipping algorithm in OFDM system, according to the characteristics of NC-OFDM system, a PCF algorithm is proposed in this paper. The simulation results show that the PCF algorithm can effectively reduce the PAPR about 0.7dB compared with the PTS algorithm while guaranteeing a certain bit error rate.
