Robust Power Control for Amplify-and-Forward Relaying Scheme

Power control problem is investigated for amplify-and-forward cellular relay network in this letter. Since the wireless channels vary with time, we aim at a power allocation scheme that is robust to the fluctuations. An optimization problem is formulated which targets at utility maximization subject...
