Reconfigurable Intelligent Surfaces for Communications and Sensing: Signal Processing and Learning Techniques
Abstract: The upcoming 5G networks and beyond are positioned as global communications system with low latencies to enable the tactile Internet with several interesting use cases. The open research question is the trade-off between latency, throughput, and resilience under further constraints such as security, energy, and heterogeneity. In this context, reconfigurable intelligent surfaces (RIS) are being considered for future generation wireless systems and are already rapidly enabling novel applications in sensing and communications such as non-line-of-sight coverage, index modulation, polarization modulation, and adaptable patterns. This tutorial introduces the audience to these recent developments in RIS-aided wireless media through well-structured presentation format covering the key signal processing elements as well the use of learning-based techniques in the design of RIS-based systems.
