Abstract :
Orthogonal Frequency Division Multiplexing (OFDM) is proven technology in modern wireless communication because of its high data rate, more immunity to delay spread. In this paper, we proposed probabilistic threshold Selective Mapping Technique which has low PAPR. The simulation result shows that modified technique has better PAPR reduction performance.
