OFDM Communication System MATLAB Simulation

After extensive searching online, I eventually obtained this MATLAB simulation program for OFDM communication systems. The acquisition required significant time and effort, but the result proved highly valuable for my research needs. This implementation includes key components such as QAM modulation/demodulation, IFFT/FFT operations for orthogonal subcarrier generation, cyclic prefix insertion/removal for mitigating inter-symbol interference, and channel modeling with additive white Gaussian noise (AWGN). The simulation allows comprehensive analysis of OFDM system performance, including bit error rate (BER) calculations under various signal-to-noise ratio conditions. This program provides crucial insights into OFDM working principles, particularly regarding how parallel data transmission through orthogonal subcarriers improves spectral efficiency and robustness against multipath fading. I anticipate applying these simulation results to practical projects involving wireless communication system design and performance optimization. The obtained code serves as an excellent foundation for both academic research and real-world implementation of multicarrier communication systems.
