In this paper we study the problem of relay-enhanced cell (REC) coverage for which relay location is optimized to maximize the achievable REC radius. The problem is investigated for both Rayleigh and Rician relay fading channels, under a pre-determined user's outage probability constraint. We propose a statistical approach to formulate the problem and develop an optimization algorithm for it. The...
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...
