Low Complex PAPR Reduction Schemes for OFDM Systems In this thesis, three low-complex PAPR reduction schemes for OFDM systems are proposed. All the proposed schemes can be considered as modified versions of the conventional SLM scheme, which can significantly reduce high PAPR of OFDM signals with no distortion.
