摘要：
In this paper, a statistical analysis of the peak-to-average power ratio (PAPR) of Polynomial cancellation coded OFDM (PCC-OFDM) signals is presented. PCC-OFDM has the good performance of compressing intercarrier interference (ICI) at the cost of high PAPR. The most PAPR analysis assume the subcarriers to be identically and independently distributed (i.i.d). However, the correlation between adjacent pairwise subcarriers of PCC-OFDM causes the assumption not valid. The adjacent partial transmit sequence (PTS) with parameter constraints can be used to reduce the PAPR of PCC-OFDM. The simulation results show that the theoretic analysis is very close to experimental results. The PAPR of PCC-OFDM signals with 128 subcarriers exhibit near 2dB higher than the same type normal OFDM. PTS based method proposed in this paper can reduce the PAPR of PCC-OFDM to the normal complex-value OFDM level while keeping PCC relation.
