PTS Algorithm Source Code for PAPR Reduction in OFDM Systems

By employing different modulation techniques and signal processing algorithms, we can effectively reduce the Peak-to-Average Power Ratio (PAPR) in OFDM systems. The Partial Transmit Sequence (PTS) algorithm is a widely adopted approach that partitions the original signal into multiple sub-blocks and applies phase weighting factors in the time domain to achieve PAPR reduction. Our MATLAB implementation demonstrates the algorithm's workflow through key functions including signal segmentation, phase optimization using intelligent search methods, and peak power calculation. The simulation successfully verifies the algorithm's effectiveness by comparing PAPR performance metrics before and after processing. This source code provides engineers with practical insights into PTS algorithm implementation, featuring modular code structure with clear comments on optimization techniques and parameter configuration, enabling better understanding and application for OFDM system performance enhancement.
