This M Code simulate the effects of clipping and filtering on PAPR reduction in OFDM-based wireless standard.Also the performance of BER versus SNR of original OFDM signals with PAPR reduction based on clipping and filtering schemes over AWGN channel

该程序实现了使用非线性压扩函数对OFDM信号进行压扩变换，并对其在AWGN下的误码性能进行了测试。-This manuscr ipt exploit the nonlinear companding function to reduce the PAPR in OFDM system, and test the BER performance in AWGN channel
