Abstract
In several wireless communication systems and standards, Orthogonal Frequency Division Multiplexing (OFDM) is used widely due to its high spectral efficiency, high data rate, multipath delay spread tolerance, power efficiency, robustness to multipath fading channels and immunity to the frequency selective fading channels. However, the main challenge for OFDM system implementation is high PAPR, which results from large envelope fluctuation in OFDM signals. In this paper, we present an analysis of PAPR reduction using class III SLM and conventional SLM methods for 4G wireless networks. Simulation results shows that class III SLM method provides a better PAPR reduction than conventional SLM method especially at high data rates.

Keywords- Class-III selected mapping (SLM), Orthogonal frequency division multiplexing (OFDM), Peak-to average power ratio (PAPR), Conventional selected mapping.
