A Weighted OFDM Signal Scheme for Peak To Average Power Ratio Reduction Of OFDM Signals

C.Kayalvizhi, C.Paranitharan

To reduce the Peak to Average Power Ratio (PAPR) in OFDM system using Genetic Algorithm (GA) based approach and also reduce its complexity by the reducing the number of iteration. Basically OFDM has several attributes for high speed wireless communication. However the increased PAPR of the signal is main drawback of OFDM signal which restricts the efficiency of transmitter. So this paper is focused in the domain PAPR reduction of OFDM signals by using weighted OFDM signal scheme.
