Full-Duplex Integrated Sensing and Communication Systems: Principles, Key Technologies, and Receiver Design

Du, Changhao, Zhang, Zhongshan, An, Jianping, Zh ● 2026

This book focuses on full-duplex integrated sensing and communication (ISAC) systems, a fast-emerging area where radios simultaneously transmit, sense, and communicate. It emphasizes the core principles, enabling technologies, and receiver architectures needed to manage self-interference and support advanced radar-communications coexistence.

Why Read This Book

Read this book if you want a technical guide to one of the most active research directions in wireless systems: combining sensing and communication in the same hardware and spectrum. It should be especially valuable for understanding receiver design tradeoffs, interference suppression, and the signal-processing challenges that make full-duplex ISAC practical.

Who Will Benefit

Best suited for RF/DSP engineers, wireless researchers, radar and communications system designers, and graduate students working in 6G, MIMO, full-duplex, or integrated sensing platforms. It will also be useful for engineers building advanced receiver chains, cancellation algorithms, or spectrum-sharing systems.

Level: Advanced — Prerequisites: Readers should already be comfortable with digital signal processing, communication theory, basic radar concepts, RF front-end terminology, and linear systems. Familiarity with MIMO, OFDM, estimation theory, and self-interference cancellation will make the material easier to follow.

How It Compares

Compared with broader DSP or wireless communication textbooks, this book is much more specialized and system-oriented. It is likely closer in spirit to advanced monographs on full-duplex radios, radar-communications coexistence, or 6G ISAC than to general references on FFTs, filtering, or audio DSP; its main value is in receiver and architecture design rather than foundational signal processing.
