MATLAB Implementation of MIMO-OFDM Simulation with Complete Channel Modeling

This comprehensive MIMO-OFDM simulation program provides a powerful platform for wireless communication system analysis. The implementation includes complete channel simulation modules with configurable parameters for path loss, fading characteristics, and noise modeling. The channel estimation component employs advanced algorithms like LS (Least Squares) or MMSE (Minimum Mean Square Error) techniques to recover transmitted signals under various channel conditions. Key functional modules support customizable antenna configurations (e.g., 2x2, 4x4 MIMO setups), adaptive modulation schemes (QPSK, 16-QAM, 64-QAM), and cyclic prefix implementation for OFDM synchronization. The code architecture allows performance metrics calculation including BER (Bit Error Rate), spectral efficiency, and throughput analysis under different SNR conditions. Researchers and engineers can leverage this simulation environment to optimize system parameters, compare algorithm performance, and validate theoretical models through Monte Carlo simulations. The modular design facilitates easy integration of new channel models, precoding techniques, and detection algorithms. Ideal for both academic research and practical wireless system development, this toolkit enables deep exploration of MIMO-OFDM advantages, limitations, and optimization strategies through flexible parameter tuning and algorithm testing.
