摘要:: 系统资源的优化分配是提升卫星通信系统容量和用户业务满足度的重要技术手段之一,也是卫星通信课程教授的重点内容。影响卫星通信系统资源分配的因素复杂且动态变化,但现有的课程教学大多以静态条件下的资源分配为主,也很难建设以实物为主的卫星通信教学环境,而且传统的理论教学直观性不强,不利于学生掌握相关知识点。为直观演示多种条件变化下的卫星资源分配,提升学生的学习兴趣,基于 MATLAB 软件利用图形用户界面工具设计开发了卫星资源动态分配教学演示软件,涵盖用户业务需求、链路雨衰、频谱资源等条件变化下的资源分配,并进一步设置了不同的资源分配算法进行对比分析。该教学软件可交互性强、直观性强、架构灵活,并在设计过程中贯彻组件化、模块化、接口化思想。实际教学效果表明,该软件对卫星资源分配的仿真效果良好,可以更好地辅助教师授课、帮助学生掌握知识点。

Abstract:: The optimal allocation of system resources is one of the important methods to improve the capacity of satellite communicationsystem and the satisfaction of users＇requirement,　which is also the key content of satellite communication course. The factors affectingthe resource allocation of satellite communication are complex and dynamic, but the existing teaching content mainly focuses on theresource allocation in the static conditions. It is also difficult to build a teaching environment for satellite communication based onphysical equipment and the traditional theoretical teaching is not intuitive. In order to visually demonstrate the allocation of satelliteresources under various conditions and enhance students＇learning interest,a teaching demonstration software for dynamic allocation ofsatellite resources was designed and developed by using graphical user interface tools based on MATLAB software, including user＇straffic requirements,rain attenuation,spectrum resources and other conditions. Furthermore,different resource allocation algorithms are setup for comparative analysis. The teaching software is highly interactive,intuitive,flexible,and carries out the idea of componentization,modularization,and interface in the design process. The actual teaching results show that the software has a good simulation effect onsatellite resource allocation,and can better assist teachers in teaching and help students master knowledge points.
