演讲标题:Intelligent Reflecting Surface Empowered 6G Wireless Networks
摘要: Deepfakes are artificially created media posing as actual video recordings and are a potential source of fake news or disinformation. Although research has been done in developing algorithms for the automatic detection of deepfakes, there needs to be more work conducted on how users identify deep fakes. This is a critical missing link because algorithms are currently not performing at a level where human judgement is unneeded. This presentation will discuss the verification strategies users adopt when engaging with content from deepfakes and the implications on businesses and societies.In this talk, we introduce a new wireless research paradigm by employing a massive number of low-cost passive reflecting elements with controllable phase, named intelligent reflecting surface (IRS), which is able to smartly change the wireless signal propagation to enable various functions such as beamforming and interference nulling/cancelation. We illustrate the main applications of IRS in achieving spectrum and energy efficient as well as secure and sustainable wireless networks in the future, and its advantages as compared to existing technologies such as massive MIMO and active relaying. We then present the signal and channel model of IRS by taking into account its hardware limitation in practice. Next, we focus on discussing the main design challenges in IRS-aided wireless networks, including joint active and passive beamforming optimization, channel estimation, etc., and highlight important directions for sensing, powering and computing.

演讲标题:Toward Enhanced Wireless Communications: Leveraging Reconfigurable Intelligent Surfaces (RIS) and End-to-End Machine Learning
摘要: In the rapidly evolving landscape of wireless communication networks, the emergence of Reconfigurable Intelligent Surfaces (RIS) stands as a game-changer. These surfaces, empowered by intelligent algorithms, offer unprecedented control over electromagnetic wave propagation, promising to revolutionize communication efficiency and coverage. RIS introduces a paradigm shift in the way we conceive and implement wireless communication systems. By strategically deploying passive reflecting elements, RIS optimizes signal transmission, mitigates interference, and enhances overall network performance. However, to fully unlock the capabilities of RIS, seamless integration with machine learning is imperative.
End-to-end (E2E) machine learning algorithms provide a holistic approach to optimizing the performance of RIS-enabled communication networks. These algorithms leverage vast amounts of data to autonomously adapt RIS configurations, channel allocation, and beamforming strategies, thereby achieving optimal performance under dynamic and complex operating environments. Through E2E machine learning, RIS networks can continuously learn from real-world interactions, evolving to meet evolving communication demands.
In this presentation, we will explore the key challenges and opportunities in deploying RIS with E2E machine learning. We will discuss the intricacies of training machine learning models to effectively harness the capabilities of RIS, ensuring seamless integration with existing network infrastructures. Moreover, we will highlight promising applications of RIS-E2E machine learning in various domains, including 5G/6G networks, IoT connectivity, and smart city initiatives. Join us as we embark on a journey to unlock the full potential of RIS through E2E machine learning. Discover how this convergence of technologies is poised to redefine the future of wireless communication networks, ushering in an era of unprecedented connectivity, efficiency, and innovation.
