A Comparative Study of PAPR Reduction Techniques in OFDM Systems: Simulation-Based Analysis and Performance Evaluation

This paper presents a comparative study of Peak-to-Average Power Ratio (PAPR) reduction techniques in Orthogonal Frequency Division Multiplexing (OFDM) systems using simulation-based analysis and performance evaluation. The focus is on investigating the effectiveness of Partial Transmit Sequence (PTS) and Discrete Fourier Transform Spread Spectrum (DFT-SS) techniques. To enhance engineering applicability in OFDM system, a C programming approach is adopted, addressing high PAPR limitations found in existing techniques. Theoretical derivations guide the development of a simulation program, and experiments with varying parameter settings are conducted. The results demonstrate significant improvements in PAPR reduction achieved by PTS and DFT-SS techniques in OFDM systems. A comparison with MATLAB results confirms the feasibility and accuracy of utilizing C programming for PAPR reduction research. This study provides valuable insights for the design and optimization of high-performance OFDM systems, offering innovative perspectives and methodologies for practical implementation.
