OFDM is successfully used in many wireless digital communication system over multipath channels. One of the principle disadvantages of OFDM is the occurrence of high PAPR. OFDM signals are very sensitive to nonlinear effects due to the high PAPR, which leads to the power inefficiency in the RF section of the transmitter. This paper is focused on analyzing PAPR reduction by undertaking various methods to reduce the PAPR in the system PTS, Companding and a hybrid DCT-PTS-Companding. Simulation results show that the proposed hybrid method outperforms other methods of PAPR reduction.
