Detailed Documentation
The MATLAB script "SLM_Papr_V4.m" implements the Selected Mapping (SLM) technique version 4 to analyze the Peak-to-Average Power Ratio (PAPR) characteristics through Complementary Cumulative Distribution Function (CCDF) curves. The algorithm generates multiple phase rotation sequences (V=4 candidate sets) to create alternative OFDM signal representations, selecting the version with minimum PAPR. Key functions include: phase sequence initialization using random permutation, IFFT-based signal transformation, and PAPR calculation with CCDF plotting. This implementation provides crucial insights into PAPR probability distribution, enabling communication engineers to optimize system performance by evaluating SLM's effectiveness in reducing peak power requirements. The CCDF visualization helps quantify the probability that PAPR exceeds specific thresholds, essential for designing power-efficient wireless communication systems.
