Abstract: In the revolution and advancements of wireless communications, the Orthogonal Frequency Division Multiplexing (OFDM) plays a major role. The main drawbacks of OFDM are Inter-Symbol Interference (ISI) and Inter Carrier Interference (ICI), will degrade its performance, motivates the idea for reducing PAPR. In order to improve the performance of 4G-LTE system, PAPR has to be minimized hence various reduction schemes of PAPR such as Selective Mapping (SLM), Clipping and Filtering (CLF), and Partial Transmit Sequence (PTS) are discussed in this paper. This paper aims at the performance comparison of various reduction schemes of PAPR. Complementary Cumulative Distribution Function (CCDF) plots are used to figure out the best reduction scheme. From simulation results, it is observed that CCDF and PAPR of original signal are 0.875 and 10.61, with CLF 0.75 and 8.42, with SLM 0.75 and 9.695, with PTS 0.75 and 4.43 respectively. Hence, PTS gives better performance when compared to other schemes.
