Abstract

Peak to average Power Ratio (PAPR) is the major drawback of orthogonal Frequency Division Multiplexing (OFDM) systems. Since OFDM is the indispensable technology for 4G wireless schemes, great attention is given to PAPR reduction. Some of the techniques classified under signal distortion and signal scrambling already existing to meet the needs, but their effectiveness is still a question for research. In this background this paper presents a new –composite scrambling-technique which combines SLM, clipping and peak windowing methods. Comparative analysis of this proposed system with different PAPR reduction techniques are done and the advantages are discussed with their tread offs. MATLAB programming is used for simulation.
