Abstract: With the depletion of spectrum, wireless communication systems turn to exploit large antenna arrays to achieve the degree of freedom in space domain, such as millimeter wave massive multi-input multi-output (MIMO), and reconfigurable intelligent surface (RIS) assisted communications. Meanwhile, it has been recently admitted that implementing deep learning (DL) into large-scale antenna communications will extensively benefit the system capacity and enhance the robustness to complicated transmission environments. Different from traditional model-driven approaches, DL can help deal with the existing communications and signal processing problems in a data driven perspective by digging the inherent characteristic from the real data. Thus, DL is particularly suitable for large-scale antenna systems under unideal scenarios like modeling mismatching, insufficient resource, hardware impairment, as well as dynamical transmissions. Motivated by this, this tutorial aims to provide the audience a general picture of the recent developments in this exciting area. Specifically, in this interactive presentation we will introduce the merging of DL and large-scale antenna systems, over various topics, including channel acquisition, signal detection, and beam forming design, etc. We will also discuss the challenges of DL empowered large-scale antenna systems and present some interesting future directions.
