最小功耗的中继选择与功率分配的联合优化
Joint power allocation and relay selection strategies based on minimizing power consumption for relay networks
摘要
Abstract
This paper investigates several joint power allocation and relay selection strategies for wireless cooperative networks with Amplify-and-Forward(AF) protocols. These strategies aim at minimizing the total power consumption subject to some given Quality of Service(QoS), which can be formulated to convex optimization problems. Using standard convex optimization techniques, closed-form solutions to these problems are obtained. Simulation results show that the proposed strategies can achieve lower power consumption than the traditional random relay selection and equal power allocation strategy.关键词
