Abstract: Orthogonal Frequency Division Multiplexing (OFDM) system is a multicarrier system used to transfer data at high rate. One of the drawbacks of OFDM is the high value of Peak to Average Power Ratio (PAPR). High PAPR values will mitigate the ef?icacy of the power ampli?ier. This paper discusses the Wavelet-OFDM with Partial Transmit Sequence. The use of wavelet transformation on the OFDM system provides several advantages compared to Fourier transform. These advantages include high ef?iciency due to the loss of guard interval (GI). The proposed Wavelet-PTS system reduces the PAPR signi?icantly, which can achieve a reduction of 8 dB PAPR compared with the conventional OFDM system.
