MATLAB-Based Design and Simulation of MIMO-OFDM Communication Systems

This project provides MATLAB source code for designing and simulating MIMO-OFDM communication systems. The implementation incorporates multiple-input multiple-output antenna configurations and orthogonal frequency-division multiplexing techniques. The simulation includes comprehensive analysis of channel transmission, signal modulation/demodulation processes, and bit error rate performance evaluation to ensure system reliability and performance optimization. Key implementation aspects include: - Channel modeling with spatial multiplexing for MIMO configurations - OFDM modulation/demodulation using FFT/IFFT operations - BER calculation through Monte Carlo simulations - Constellation mapping for different modulation schemes (QPSK, 16-QAM, etc.) The code structure allows for easy integration of additional features such as channel estimation algorithms (LS, MMSE methods) and adaptive modulation techniques that can dynamically adjust modulation schemes based on channel conditions. The modular design enables researchers to test various system parameters and evaluate performance under different channel scenarios, making it suitable for wireless communication system development and academic research.
