摘要
先进的长期演进技术(long term evolution advanced,LTE-advanced)是新一代无线移动通信系统核心技术,如何有效评估这一技术系统性能是当前研究重点之一。在充分理解无线通信系统级仿真基本理论和LTE-advanced系统级仿真若干规范基础上,梳理LTE-advanced系统级仿真涉及的组织结构,采用模块化设计方法,以此结构为框架搭建系统级仿真平台,实现对LTE-advanced进行系统级仿真。进一步以LTE-advanced系统重要性能参数平均吞吐量为考察指标,重点分析对比了轮询、最大载干比、比例公平这3种调度算法对LTE-advanced网络整体性能的影响。
LTE-advanced is the core technology of next generation wireless mobile communication system, and one of the concentrations in current research is how to assess the performance of this technology effectively. This paper, based on the understanding of the basic theory of wireless communication system-level simulation and a number of specifications about LTE-advanced system-level simulation, cards the organizational structure involved in LTE-advanced system-level simula- tion, employs the modular design, taking the above mentioned structure as a framework to build the system-level simulation platform, and achieves the LTE-advanced system-level simulation. Furthermore, using key performance parameter of LTE- advanced system-- average throughput as the indicators, this paper analyzes and compares the influence of round robin, best eqi and proportional fair scheduling algorithm in LTE-advanced network overall performance.
