摘　　要：在充分理解无线通信系统级仿真以及超密集Small Cell技术的基础上,利用Visual Studio 2010实现了Small Cell的三维双带模型,搭建了面向未来超密集Small Cell网络的系统级仿真平台。仿真验证了平台中的Small Cell双带模型拓扑结构,重点分析了3GPP提出的3种功率控制方案对超密集Small Cell网络性能的影响。仿真结果表明,功率控制方案的仿真性能与理论分析相吻合,证实该平台达到了系统设计的相关要求。该仿真平台为分析超密集Small Cell网络的性能提供了技术手段,评估结果对Small Cell前期部署及后期优化具有指导意义。Based on the full understanding of the basic theory in wireless communication system-level simulation and Small Cell network, the 3D dual strip model of Small Cell is achieved, and a system-level simulation platform using the Visual Studio 2010 for ultra-dense network with Small Cell is built. The dual strip model has been verified, and the impact of three kinds of power control scheme proposed by 3GPP on uhra-dense network with Small Cell has been analyzed on the simulation platform. The simu- lation results of power control coincide with the theoretical analysis, which confirms the platform has met the requirements of the system design. Furthermore, the overall perfnrnmnce of Small Cell-based ultra-dense networks can be evaluated through the simu- lalion platform, which benefits us to deploy Small Cell and optimize the performance of the ultra-dense networks.
