PAPR Reduction Using Constellation Extension Method with MATLAB Implementation

This program is a MATLAB simulation that implements the constellation extension method for peak-to-average power ratio (PAPR) reduction in OFDM systems. The implementation statistically analyzes 100,000 OFDM symbols to characterize the algorithm's effectiveness in improving PAPR performance. The code has been thoroughly tested and guarantees stable execution. The primary objective of this program is to demonstrate PAPR suppression using constellation expansion techniques and evaluate the algorithm's improvement level through statistical analysis of a large dataset of OFDM symbols. Through this simulation, you can gain better understanding of MATLAB implementation techniques and research methodologies for addressing PAPR issues in signal processing systems. The code includes key functions for constellation mapping, IFFT operations, and PAPR calculation with complementary cumulative distribution function (CCDF) analysis. You can modify and optimize the program according to your specific research or application requirements. The implementation features modular design with clear separation between constellation extension logic, OFDM symbol generation, and performance evaluation modules. The program has undergone rigorous testing to ensure operational stability and numerical accuracy. We hope this program proves valuable for your research or professional work in wireless communications and signal processing. The code structure allows easy integration of additional PAPR reduction techniques and supports parameter customization for different modulation schemes and system configurations.
