MATLAB Simulation of OFDM Application in WLAN

To support engineering professionals and graduate students in developing OFDM-based wireless local area networks, I provide MATLAB source code for simulating OFDM applications in WLAN environments. This implementation includes fundamental OFDM processing blocks: QAM modulation for data mapping, IFFT transformation for orthogonal subcarrier generation, cyclic prefix insertion to mitigate inter-symbol interference, and channel modeling for realistic wireless conditions. The code enables comprehensive understanding of OFDM principles in WLAN systems, including frame structure, synchronization techniques, and equalization methods. Through this simulation platform, users can conduct various experiments and parameter adjustments to optimize OFDM system performance, analyze bit error rate (BER) characteristics under different channel conditions, and evaluate spectral efficiency improvements. The modular code structure allows easy customization of parameters like FFT size, cyclic prefix length, and modulation schemes, facilitating both educational demonstrations and practical system development. This resource aims to accelerate research and development efforts in enhancing WLAN performance and reliability through OFDM technology implementation.
