Abstract

In this paper we consider the joint resources allocation in multiple channels single non-regenerative (AF) relay systems. Firstly, the optimization problem of maximizing system capacity under joint power constraint at source and relay is formulated. We adopt Lagrangian dual method to derive the optimal centralized algorithm. Through the analysis it is proven an efficient and computational tractable scheme.
