The probability distribution and bit error rate performance of PAR of OFDM signal are analyzed when adopt this method. And the degrees of reduction of PAR of OFDM signal with different limiter factor and impulse factor are simulated. 分析了采用此方法的OFDM信号峰平比的概率分布和误码率性能,对冲激脉冲相消法中不同限幅因子和冲激比因子对OFDM信号的峰平比降低的程度进行了仿真。
