Title
Performance Analysis of PAPR Reduction Techniques for OFDM signals in DVB-T System
Abstract
Digital Video Broadcast-Terrestrial is the most extensively employed standard for terrestrial digital television (TV). The DVB-T system is based on OFDM and it has the problem of high Peak to Average Power Ratio (PAPR). One way to mitigate the high PAPR is by using efficient PAPR reduction techniques. In this paper, we analyze and compare the performance of different PAPR reduction techniques of OFDM based on implementation complexity, bandwidth expansion, BER degradation and data rate loss. Also we investigate the effects of High power amplifier (HPA) and channel noise on the OFDM signals with QAM modulation and Performance study/analysis of selective mapping as a reduction technique for PAPR with phase rotation is carried out using MATLAB 7.10.0(R 2010a).
