Abstract

This chapter offers a systematic investigation into cross-modal communication, a promising research area supporting multi-modal services. It introduces the characteristics of current and future multi-modal services and presents a general cross-modal communication architecture. The text delves into three key techniques: cross-modal coding, transmission, and signal recovery, highlighting their challenges and design principles. Notably, it derives optimal coding rates and presents prototype systems demonstrating potential in remote industrial control, education, and healthcare. The chapter also explores extended directions, such as cross-modal semantic communications and solutions for extremely low-resource scenarios. Future research directions are discussed, emphasizing the need for integrating olfactory and gustatory modalities and utilizing natural interactions among human sensory subsystems. The chapter concludes by suggesting the potential of cross-modal communication technology to inspire solutions in other fields, such as smart education.
