In wireless communication peak to average power and channel estimation are important parameters which should be considered for efficient communication. At the receiver end, the signal is normally distorted due to channel interference and noise. In this paper we focus on complete analysis of PAPR and channel estimation in wireless communication. For this purpose we use discrete Fourier transform which has many application. In this paper we analyze the effect of increase in number of subcarrier on the performance of PAPR using discrete Fourier transform technique. The paper also describes how discrete Fourier transform can be used to remove the distortion from received signal. Our main motive is to improve the peak to average power ratio with the help of discrete Fourier transform approach. This will improve the power efficiency. All the mathematical equations and simulation for our analysis are done with the help of MATLAB software.
