... the information theoretic rates. This impliesthat the optimization technique used in this paper can beincorporated as a building block in a variety of resource allocation settings.Lastly, in ... by fixing the overall band for this linkand performing joint power and bandwidth optimization.Therefore, as long as the relay-to-destination SNRs aredifferent, which is usually the case in practice, ... alternating maximization algorithm thatcalls for optimizing α= {α1, α2} in one stage, followed byoptimizing φ={φ1, φ2, φ3} in the next stage. The iterationsare obtained by finding KKT...
