Cooperative MIMO System Simulation with MATLAB Implementation

This MATLAB implementation provides a complete simulation environment for Cooperative MIMO relaying systems, featuring multi-antenna configurations and cooperative communication protocols. The codebase includes fundamental components such as channel modeling using Rayleigh or Rician fading distributions, signal transmission with precoding techniques, relay processing algorithms, and receiver combining methods. Researchers can modify system parameters including antenna array sizes, relay selection strategies, power allocation schemes, and modulation techniques to analyze key performance metrics like bit error rate (BER), channel capacity, and coverage enhancement. The simulation framework implements cooperative diversity algorithms such as amplify-and-forward (AF) or decode-and-forward (DF) protocols, allowing comparison of different relaying strategies under various channel conditions. Key functions include channel matrix generation, cooperative beamforming calculations, and performance evaluation modules that output graphical results for system optimization. This MATLAB toolkit serves as an essential resource for designing efficient transmission schemes, evaluating the impact of different channel models, and understanding the trade-offs between complexity and performance in cooperative MIMO systems. The modular code structure enables easy integration of custom algorithms and extensions for advanced research in wireless communication systems.
