OFDM Transmitter Implementation with GUI and Statistical Analysis

In this project, I have implemented the OFDM transmitter architecture and developed a comprehensive GUI interface for system interaction and visualization. The implementation includes MATLAB-based signal processing modules that handle key OFDM operations such as serial-to-parallel conversion, IFFT transformation, cyclic prefix insertion, and digital-to-analog conversion. The statistical analysis component generates and plots four critical performance metrics: Probability Density Function (PDF) to show signal amplitude distribution, Peak-to-Average Power Ratio (PAPR) to analyze power efficiency, Cumulative Distribution Function (CDF) for probability analysis, and Complementary Cumulative Distribution Function (CCDF) to evaluate peak power characteristics. Additionally, I conducted detailed performance analysis with focus on algorithm optimization and system robustness. The visualization framework employs MATLAB's plotting functions with customized axes labeling and interactive GUI elements for real-time parameter adjustment. Several enhancements were implemented to improve system performance and stability, including optimized FFT windowing techniques and improved error handling mechanisms in the signal processing chain.
