Performance Evaluation of PAPR Reduction in OFDM System

Santhi M. Laguduva, Vidya Gogate


OFDM is a bandwidth efficient multicarrier modulation which has gained a tremendous focus in recent years because of its high spectral efficiency; multipath delay spread tolerance, effectiveness against impulse noise and frequency diversity. However, some challenging issues still remain unsolved in the design of the OFDM systems. One of the major problems is high peak-to-average power ratio (PAPR) of transmitted OFDM signals. A large PAPR brings disadvantages like increased complexity to the analog-to-digital (A/D) and digital-to-analog (D/A) converters and a reduced efficiency to the RF power amplifier. In this paper, the proposed techniques are based on modified selected level mapping and a hybrid technique used to reduce peak to average ratio of transmitted OFDM signal. And using Matlab simulation result, the proposed techniques are analyzed.
