Cooperative communication has achieved major research concern due to its ability to enlarge system coverage and improve spectrum efficiency. Consider, a transmit cooperative beamforming design, for the scenario with Multiple-Input-Multiple-Output (MIMO) Decode-and-Forward (DF) relay channel with a direct source to destination link. The achievable information rate (bits/s) for a given transmit Signal-to-Noise Ratio (SNR) for a particular beamforming scenario is calculated based on the optimal beamforming vectors obtained. Results show that when multiple numbers of antennas are deployed at all the nodes the achievable information rate is higher.
