英文摘要： After fast developing for decades, wireless cellular communication systems gradually come across the bottlenecks of network capacity and energy consumption. It is a great challenge to increase the network capacity under the constraints of limited spectrum resources and energy consumption. The layered heterogeneous networks (HetNet,Heterogeneous Networks) is an effective approach to solve the problems.Combined with cooperative communication and radio cognitive technology, this project investigates the resource allocation of layered HetNet to meet the requirement of energy efficiency and quality of service of users. Specially, we mainly focus on the following research works:(1)the analysis of coverage and energy efficiency for layered HetNet based on cognitive radio technology;(2)the optimal transmit scheme and selection based on cognitive technology;(3)the resource allocation and energy-efficient strategies of layered HetNet. The outcome of our research can provide valuable technical references for applying cooperative and cognitive radio technologies in wireless cellular networks, and can provide theoretical support for obtaining energy-efficient layered HetNet.
