MATLAB Code Implementation for OFDM Simulation

This OFDM simulation program is implemented using MATLAB. It serves as an educational and analytical tool to help users better understand the principles and applications of OFDM technology. The code architecture includes modules for signal generation, IFFT/FFT operations, cyclic prefix insertion/removal, and channel modeling. Users can simulate and analyze OFDM system performance under various parameters, including bit error rate (BER), signal-to-noise ratio (SNR), and spectral efficiency metrics. The implementation allows customization of key parameters such as subcarrier count, modulation schemes (QPSK, 16-QAM, etc.), and channel conditions. Through this simulation program, users can gain in-depth knowledge of OFDM technology and perform optimization and improvements for practical applications. The code includes visualization capabilities for spectrum analysis and error performance plotting. We hope this program proves beneficial and inspiring for both learning and research purposes.
