Integrated sensing and communication (ISAC) holds immense potential as the primary trend and enabling technology for the upcoming era of wireless networks, known as 6G. By seamlessly integrating sensing and communication functionalities, ISAC aims to enhance spectrum efficiency, hardware efficiency, and information processing efficiency. However, despite its promising advantages, ISAC faces several limitations, such as limited coverage due to high-frequency signals and constrained communication-sensing performance in uncontrolled wireless environments.

To overcome these deficiencies, reconfigurable intelligent surfaces (RIS) emerge as a novel solution. RIS intelligently manipulate the wireless propagation environment, enabling energy- and hardware-efficient reconfiguration of the radio frequency (RF) landscape. This innovative approach promises to revolutionize ISAC by improving communication capacity, sensing accuracy, and coverage.

In this book, we delve into the realm of RIS-enabled ISAC from three crucial perspectives: performance analysis, beamforming design, and signal processing. We provide a comprehensive introduction to RIS-enabled ISAC, encompassing its basic concepts, motivations, potential application scenarios, and an overview of the state-of-the-art research in this field. We also discuss the theoretical performance analytical frameworks employed in RIS-enabled ISAC and present the corresponding results.

Furthermore, we identify and elaborate on several critical issues related to RIS-enabled ISAC, including signal processing technologies such as angle and Delay-Doppler information acquisition and air interface technologies such as beamforming designs. We explore the latest advancements and challenges in these areas, highlighting the potential solutions and future directions for RIS-enabled ISAC.

Finally, we conclude the book by summarizing the key insights and takeaways from our discussions. This book aims to serve as a valuable resource for researchers, engineers, and practitioners interested in advancing the capabilities of RIS-enabled ISAC and shaping the future of wireless communication systems.
