PAPR reduction of OFDM using recurring SLM with cyclic block codes schemes

Orthogonal Frequency division multiplexing (OFDM) is a type of multicarrier modulation (MCM) technique which plays an important role in 4^th generation of wireless network. One major flaws present in this method is high Peak to Average power ratio (PAPR). A modified SLM technique using cyclic block codes is presented in this paper. The simulation study verifies that the PAPR reduction by proposed method (modified SLM) is better than the existing technique (SLM).
