Optimal Power

The paper sudies the transmit power optimization for cooperative multiple-input multiple-output (MIMO) systems using amplify-and-forward (AF) technique. The suty examines and evaluates the system in which the communication between the sourece and the multi-antenna equipped destiation is helped by multi relay nodes. To further improve the perfornamce of the system, the optimal power allocation between the source and relay(s) is also considered. In terms of outage probalblity, numerical results show that cooperative communication systems using optimal power allocation profile outperform those with uniform power allocaion profile.
