Complete OFDM System Model and MATLAB Simulation Program

This is a highly detailed graduation project that thoroughly elaborates the complete OFDM system model and MATLAB simulation programs. The design covers the following key aspects: 1. Fundamental principles and working mechanism of OFDM systems, including mathematical formulations for orthogonal subcarriers and spectral efficiency advantages. 2. Complete system model of OFDM, with detailed descriptions of both transmitter and receiver modules - covering signal mapping, IFFT/FFT operations, cyclic prefix insertion, channel estimation, and synchronization techniques. 3. Performance analysis of OFDM systems, including simulation results for critical metrics like Bit Error Rate (BER) vs Signal-to-Noise Ratio (SNR) under various channel conditions. 4. MATLAB simulation implementation featuring code structure explanation, key functions such as qammod(), fft(), ifft(), and visualization of simulation results through plotting functions. 5. Discussion on optimization and improvement methods for OFDM systems, including peak-to-average power ratio reduction techniques and channel equalization algorithms. This graduation project is based on in-depth research and analysis of OFDM systems, aiming to provide comprehensive theoretical foundations and practical guidance. It enables readers to better understand and apply OFDM technology through hands-on MATLAB implementation. The project serves as valuable reference and inspiration for researchers and engineers in related fields, particularly those working on wireless communication systems and digital signal processing applications.
