MATLAB code implementations for amplify-and-forward and decode-and-forward cooperative communication protocols with detailed algorithm explanations and signal processing techniques

Basic Performance Analysis of DF (Decode-and-Forward) Cooperative Communications

This MATLAB program simulates the fundamental performance of cooperative communications using Decode-and-Forward (DF) protocol with an S-R-D three-node model, featuring Maximum Ratio Combining (MRC) at the receiver. Under fixed DF conditions, system performance is constrained by errors in the SR channel, preventing effective diversity gain at high SNR regimes. However, proximity between source and relay nodes may yield certain diversity advantages when the SR distance is sufficiently reduced.
