Implementation of OFDM Transmitter and Receiver Using MATLAB

In this documentation, we have implemented a complete OFDM transmitter and receiver system using MATLAB programming. Our implementation covers key aspects of OFDM technology including signal modulation, cyclic prefix insertion, IFFT/FFT operations, and channel equalization techniques. Through this hands-on programming approach, we have deepened our understanding of OFDM fundamentals while mastering essential MATLAB programming skills. The code demonstrates practical implementation of OFDM core algorithms such as: - QAM modulation and demodulation schemes - Pilot insertion for channel estimation - Cyclic prefix addition and removal for mitigating inter-symbol interference - Parallel-to-serial and serial-to-parallel data conversion We have included detailed comments and modular code structure to facilitate learning. This documentation serves as a valuable educational resource for understanding both OFDM system design and practical MATLAB implementation techniques, providing comprehensive reference material for students and engineers working in wireless communication systems.
