<p><b>Understand the cutting-edge technology of semantic communications and its growing applications</b> <p>Semantic communications constitute a revolution in wireless technology, combining semantic theory with wireless communication. In a semantic communication, essential information is encoded at the source, drastically reducing the required data usage, and then decoded at the destination in such a way that all key information is recovered, even if transmission is damaged or incomplete. Enhancing the correspondence between background knowledge at source and destination can drive the data usage requirement even lower, producing ultra-efficient information exchanges with ultra-low semantic ambiguity. <p><i>Wireless Semantic Communications </i>offers a comprehensive overview of this groundbreaking field, its development, and its future application. Beginning with an introduction to semantic communications and its foundational principles, the book then proceeds to cover transceiver design and methods, before discussing use cases and future developments. The result is an indispensable resource for understanding the future of wireless communication. <p>Readers will also find: <ul><li>Analysis of transceiver optimization methods and resource management for semantic communication</li><li>Detailed discussion of topics including semantic encoding and decoding, Shannon information theory, and many more</li><li>A team of editors with decades of combined experience in the study of wireless communications</li></ul> <p><i>Wireless Semantic Communications</i> is ideal for electrical and computing engineers and researchers, as well as industry professionals working in wireless communications.
