Recently researchers have developed many techniques to solve high PAPR problem. These techniques have some merits and demerits. The concentration of this research work is especially upon the SeLected Mapping (SLM) and Partial Transmit Sequence (PTS) techniques using wavelet transforms Inverse Discrete Wavelet Transform (IDWT) and DWT instead of conventional Fast Fourier Transforms (FFT). The Fourier transform is a powerful tool to analyze the components of stationary signals for example this transform is used to process the signals containing the combination of sine and cosine signals. But the Fourier transform is less useful to analyze the components of non stationary signals.
