摘要
根据LTE系统的原理和模块构成,分析并建立了一个基于MATLAB的系统级仿真平台。针对LTE系统中被广泛认可的轮询、比例公平和最大载干比三种经典调度算法,利用仿真平台产生的数据对三者的性能进行比较和评估。此外,针对用户不同的运动模式进行多次仿真后,得到在高速和低速场景中LTE系统平均吞吐量的变化情况并加以分析。
According to the principle and modules of LTE（Long Term Evolution）system, this paper analyzes and sets up a system level simulation platform based on MATLAB. The performance of three widely recognized classical scheduling algorithms which are RR, PF and best CQI in LTE system is compared and evaluated by using the simulation platform of data. In addition, this paper considers different movement patterns of users, and evaluates the average throughtput of LTE system in the high-speed and low-speed scenes.
