Title: Intelligent Reflecting Surfaces Assisted Wireless Communications

Abstract:

Intelligent reflecting surface (IRS) is an artificial planar structure made of sub-wavelength unit cells with adjustable electromagnetic responses, which has the potential to manipulate the propagation environments in an intelligent manner. Therefore, IRS has been envisioned as a promising technique to build spectral and energy efficient wireless communication systems, and has received considerable research interests from the community. Motivated by this, in this talk, we first introduce the basic of IRS, followed by its potential application scenarios in wireless communications. Then we elaborate on recent advances of IRS assisted communications. Finally, we discuss some important future directions.

Title: Deep Learning for Physical Layer Communications: An Attempt Towards 6G

Abstract:

Merging artificial intelligence  in to the system design has appeared as a new trend in wireless communications areas and has been deemed as one of the 6G technologies.  In this talk, we will present how to apply the deep neural network (DNN) for various aspects of physical layer communications design, including the channel estimation, channel prediction, channel feedback, data detection, and beamforming, etc. We will also present a promising new approach that is driven by both the communications data and the communication models. It will be seen that the DNN can be used to enhance the performance of the existing technologies once there is model mismatch. More interestingly, we will show that  applying DNN can deal with the conventionally unsolvable problems, thanks to the universal approximation capability of DNN. With the well-defined propagation model in communication areas, we also attempt to explain the DNN under the scenario of channel estimation and reach a strong conclusion  that DNN can always provide the asymptotically optimal channel estimations. In all, DNN is shown to be a very powerful tool for communications and would make the communications protocols more intelligently. Nevertheless, as a new born stuff, one should carefully select suitable scenarios for applying DNN rather than simply spreading it everywhere.
