Peak To Average Power Ratio (PAPR) Reduction Technique Using Selective Mapping in OFDM System

OFDM is an excellent, interference-free multicarrier modulation technique that is very efficient with the available spectrum. When practical power amplifiers are employed at the transmitter, the high peak to average power ratio (PAPR) of OFDM systems causes power inefficiency and signal distortion, which is a significant disadvantage. A distortion-free method that successfully lowers PAPR without sacrificing data speed or using more power is called selective mapping (SLM). The results of the simulation indicate that the suggested SLM strategy minimises PAPR more successfully.
