美国休斯敦大学韩竹教授于通信工程学院开展线上系列学术讲座

发布日期 :2020-11-11作者 :点击 :

20201026日至1031日,美国休斯敦大学韩竹教授与我院师生进行了为期6天的线上学术讲座交流活动,累计超过三百人次参加。讲座由胡封晔教授主持,并通过线上平台和线下会议室分会场两种方式举行。

韩竹教授的六个学术报告共包含了五个专题,分别为"Aerial Access Networks for 6G: From UAV, HAP, to Satellite Communication Networks", "Reconfigurable Intelligent Surface for 6G: Communication, Sensing, and Localization", "Modern Delay Analysis for Networking: from MCMC, Martingale to Stochastic Network Calculus, Lyapunov and Age of Information", "Federated Learning Tutorial", "Multi-Armed Bandits Its Application in Wireless Networking"。

韩竹首先介绍了空中访问集成网络的基本知识和当前空中与地面无线通信系统的应用,并指出了现在所面临的挑战。然后,他又阐述了基于Reconfigurable Intelligent Surface (RIS)技术的高速数据服务,并通过与传统天线阵列相对比,突出RIS的独特功能,深入介绍了RIS辅助通信的方式及其典型的应用程序。

下来,韩竹向师生们展示了两种新型用于替代传统排队理论的网络延迟分析方案。这两种方案分别利用了Markov Chain Monte Carlo (MCMC), Lyapunov Stability和Age of Information (AOI)原理,能够提供更准确的延时分析和系统稳定性。而为了解决云服务器所带来的延迟问题,他也介绍了移动边缘计算,并在此基础上引入联合学习概念,展示了相关仿真结果。最后,针对Multi-Armed Bandit (MAB)的基本模型和解决方案,他以多种算法为例,全面演示了实际问题的解决过程,并指出当前研究所存在的局限性以及未来的发展方向。

韩竹教授针对无线通信系统进行了十分精彩的学术报告,而对于老师和同学们的问题,他也进行了详细的解答。这种线上线下同步进行的方式使得讨论的气氛十分浓烈。本次线上学术会议开拓了同学们在无线通信领域的视野,并进一步了解了前沿的技术和知识。
