In chapter 2, the authors outline multi-modal services and a general cross-modal communication architecture, including typical service categories, communication requirements, architectural details, challenges, and design principles. In chapters 3, 4, and 5, the authors respectively propose three key techniques within the cross-modal communication architecture: cross-modal coding, cross-modal transmission and cross-modal signal recovery. For each technique, the authors provide an in-depth presentation of the representative algorithms and the related experimental results. chapter 6 describes an established database and the three developed cross-modal communication prototype systems. Chapter 7 introduces extended techniques, such as cross-modal semantic communications, cross-modal communications in extremely low-resource scenarios. Finally, the authors provide a summary of the entire book and discuss future research directions in chapter 8. The readers will gain a deep understanding of the development and technical details of this new communication paradigm for the emerging multi-modal services.
