Complete OFDM Source Code Implementation

This article presents a complete OFDM source code implementation developed in MATLAB. The codebase includes fundamental OFDM components such as QAM modulation/demodulation modules, IFFT/FFT operations for orthogonal subcarrier generation, cyclic prefix insertion/removal for mitigating inter-symbol interference, and channel estimation algorithms. Whether you're beginning your OFDM studies or are an experienced researcher, this implementation provides practical insights into OFDM principles and real-world applications. The modular code structure allows for easy customization of parameters like FFT size, cyclic prefix length, and modulation schemes. Researchers can utilize this codebase as a foundation for developing advanced OFDM systems, testing new algorithms, or conducting performance simulations under various channel conditions. This implementation serves as both an educational tool for understanding OFDM fundamentals and a development platform for enhancing your wireless communication engineering skills.
