Abstract:The techniques to achieve Peak-to-Average Power Ratio (PAPR) minimization in Orthogonal Frequency Division Multiplexing (OFDM) signals, has brought more interest among the researchers in recent days. Among various methods for PAPR reduction, the Partial Transmit Sequence (PTS) and Selected Mapping (SLM) has derived successful reduction and improvement compared to other methods. However, it requires a large complexity for obtaining a kind of good performance in PAPR minimization. Thus, it is continuously being revised and improved by the researchers to provide better results. This paper focus on the same motivation mentioned above. It includes an improved PTS with the help of new Sub-block Weighting (SW) method. The improved PTS is combined with SLM technique for diminishing the computational intricacy for OFDM system. Simulation and experimental outcome confirms that the proposed method shows a superior outcome in terms of Complementary Cumulative Distribution Function (CCDF) compared to previous schemes.
