OFDM Simulation Implementation for Graduation Project

During my graduation project, I successfully developed an OFDM simulation program with comprehensive functionality. I conducted in-depth research on OFDM technology and implemented a versatile simulation system capable of performing various analyses. The program's architecture incorporated key OFDM components including serial-to-parallel conversion, IFFT/FFT operations (implemented using efficient radix-2 algorithms), cyclic prefix insertion/removal, and constellation mapping/demapping modules. I simulated OFDM system performance under different channel conditions (AWGN, multipath fading) and analyzed critical parameters such as bit error rates across various modulation schemes (QPSK, 16-QAM, 64-QAM). The implementation included channel estimation techniques using pilot symbols and equalization methods to combat frequency-selective fading. After several months of research and development, I created a fully functional program that handled complete OFDM transmission chains from data generation through demodulation and performance metrics calculation. This project not only helped me graduate successfully but also provided deep understanding of OFDM principles and complex simulation development skills. I believe this experience with digital signal processing implementations and wireless communication simulations will be invaluable for my professional career advancement.
