Detailed Documentation

This simulation program implements the Partial Transmit Sequence (PTS) method to suppress Peak-to-Average Power Ratio (PAPR) in OFDM transmitters. The implementation involves partitioning OFDM symbols into multiple sub-blocks, applying phase rotation factors to each sub-block, and selecting the optimal combination that minimizes PAPR. Through this optimization technique, we achieve significant improvement in PAPR statistical characteristics, visualized through Complementary Cumulative Distribution Function (CCDF) curves. The program generates comparative CCDF-PAPR plots to quantify the performance enhancement provided by PTS method, featuring key functions for signal partitioning, phase optimization, and PAPR calculation. This simulation helps researchers better understand and analyze the effectiveness of PTS technique in reducing peak power ratios while maintaining signal integrity.
