Abstract
Artificial intelligence (AI) is envisioned to play a key role in future wireless technologies, with deep neural networks (DNNs) enabling digital receivers to learn to operate in challenging communication scenarios. However, wireless transceiver design poses unique challenges that fundamentally differ from those encountered in traditional deep learning domains. The main challenges arise from the limited power and computational resources of wireless devices, as well as from the dynamic nature of wireless communications, which causes continual changes to the data distribution. These challenges impair conventional AI based on highly-parameterized DNNs, motivating the development of adaptive, flexible, and light-weight AI for wireless communications, which is the focus of this talk. We will discuss how AI-based design of wireless receivers requires rethinking of the three main pillars of AI: architecture, data, and training algorithms. In terms of architecture, we will review how to design compact DNNs via model-based deep learning. Then, we will discuss how to acquire training data for deep receivers without compromising spectral efficiency. Finally, we will review efficient, reliable, and robust training algorithms which enhance existing deep learning techniques via meta-learning and generalized Bayesian learning, as well as propose different learning approach based on modelling learning dynamics as a state space model.
