In this proposed system a precoding-based PAPR reduction technique is proposed for both the UF-OFDM and the F-OFDM cases. In this system we are using the Zadoff Chu Transform for the precoding process. The input bit stream is first modulated by QAM modulation and then the precoding technique is performed. For UF-OFDM, after that the inverse discrete Fourier transform is performed on the data streams and then the filtering is applied. For the filtering operation Chebyshev filter is performed and then the data are send through the channel. And for the F-OFDM process the data are modulated and the inverse discrete Fourier transform is performed. And then the cyclic prefix is obtained and then the spectrum shaping filter is applied on the data streams. Here the considered channel is the AWGN channel. After that the reverse operations are performed. And in the performance evaluation the BER, PAPR, IAPR, Normalized (PSD) is calculated on the obtained output signal
