Abstract

Background/Objectives: The paper is classified to analyze different Peak to Average Power Ratio techniques and centered on that the PTS method is used for finding the PAPR and BER value for different partition groups. Methods/Statistical Analysis: The PAPR reduction is done using MATLAB for different blocks in PTS technique based on different partition groups. Findings: The proposed PTS method reduces PAPR for higher partition groups by doing phase optimization to each sub blocks up to 2-3 dB at the cost of good BER performance. The results are shown by plotting CCDF and error rate performance of the system that are generated from the system using MATLAB. Applications/Improvements: The proposed method used for finding PAPR and BER, uses less iterations and for each sub block the phase optimization is done. Also, by increasing the number of subcarriers the PAPR performance will get better as compared to other techniques.
