Simple MATLAB Simulation for Amplify-and-Forward Cooperative Communication

In this project, we will implement a simple MATLAB simulation for Amplify-and-Forward (AF) cooperative communication using Rayleigh fading channels to model wireless transmission. AF cooperation is a fundamental wireless communication technique that utilizes multiple cooperative nodes to enhance signal transmission quality and reliability. Our simulation will model a system with multiple cooperative nodes and analyze its performance through BER (Bit Error Rate) calculations and SNR (Signal-to-Noise Ratio) analysis. The implementation will involve key MATLAB functions such as rayleighchan for channel modeling and custom functions for signal amplification and forwarding mechanisms.

We will investigate various parameter configurations, including the number of cooperative nodes, channel fading characteristics, and power allocation schemes, to understand their impact on system performance. The simulation will incorporate mathematical models for signal processing at relay nodes, where received signals are amplified and retransmitted without decoding. Additionally, we will explore enhancement strategies such as optimal relay selection algorithms and power control techniques to further improve system performance. The code structure will include modular components for channel generation, signal transmission, relay processing, and performance metrics calculation.

Through this simulation project, we aim to deepen the understanding and practical application of AF cooperative technology, providing valuable insights for the design and optimization of wireless communication systems. The MATLAB implementation will serve as an educational tool demonstrating real-world cooperative communication scenarios with quantitative performance evaluation.
