摘要
以3GPP在技术规范中对LTE系统仿真所提要求为标准,对LTE系统级仿真的整体流程与基本框架进行了概括与分析,介绍了链路级映射的2种方法,在分析各功能模块的基础上搭建了系统级仿真平台,实现了LTE的系统级仿真。以下行调度算法为对象,通过系统级仿真平台对轮询、最大载干比和比例公平这3种经典分组调度算法进行了仿真与分析,为LTE系统级仿真平台的进一步完善和发展提供了理论参考。
The process and framework of the LTE system level simulation are summarized and analyzed with the standard of thetechnical specification proposed by 3GPP.Two methods of link-level mapping are described. Based on the analysis of the functionalmodules ,the system is constructed. Finally, the system is evaluated with the analysis of packet scheduling algorithms. The analysisprovides reference for promoting and perfecting LTE system-level simulation.
