Wireless Localization With Reconfigurable Intelligent Surfaces

Abstract

This chapter considers the design of localization algorithms for reconfigurable intelligent surface (RIS)-aided models under different practical channel model settings. Wireless localization and communication under high frequencies can lead to a high free space attenuation, and the problem can be signified under the non-line of Sight paths. The chapter illustrates the localization scenario and demonstrates both the channel model and the received signal model. To demonstrate the capability of localization algorithms to improve high-frequency communication, reflecting surfaces need to operate at the corresponding high frequency. Designing localization algorithms for RIS-aided models is one of the challenging tasks. The chapter presents derivation of the steering response for both the far-filed and near-filed. Most of the existing works consider the far-field scenario where the received signal takes a planer wavefront shape. Large arrays and surfaces with a large number of antenna elements such as the RIS have the advantage of enhancing both localization and communications.
