摘　　要：针对未来绿色通信需求,分析了无线通信系统中分布式天线的数量和位置对系统能量效率的影响.通过对系统能耗和容量的理论分析,建立了系统能量效率的理论表达式,给出在满足移动台服务质量时总能耗最小和总能耗一定时系统能量效率最大的高能效组网方案.仿真结果表明,采用高能效组网方案的分布式天线系统可以显著减小系统的总能耗,增加系统的能量效率.For the requirements of future green communication, the impacts of location and amounts for distributed antenna on the system energy efficiency are studied in wireless communication systems. Based on the analysis of energy consumption and capacity, the closed-form expression of energy efficiency is obtained, and energy-efficient networking schemes are proposed under the constraints of mobile station quality of service and total energy consumption. Simulation indicates that the distributed antenna systems with energy-efficient networking scheme can significantly reduce the total energy consumption and enhance the energy efficiency.
