Grasp the future of wireless communication with this groundbreaking introduction.

Research and development are already underway on the sixth generation (6G) of wireless communication technology. The new requirements of 6G that arise from challenging new use cases render physical layer waveforms such as CDMA and OFDM inadequate. The OTFS waveform answers these new requirements, and recent research suggests it will play a decisive role in the future of wireless communication. OTFS Modulation – Theory and Applications provides the first ever foundational textbook that introduces this growing, state-of-the-art, field of research from first principles. Beginning with a thorough discussion of the fundamental principles of OTFS, both physical and theoretical, it rigorously situates OTFS modulation in a mathematical framework analogous to more familiar waveforms. The result is a groundbreaking contribution to communication theory and a must-have volume for wireless communication researchers.

Two key aspects of the OTFS communication paradigm are responsible for its superior performance. They are (i) channel representation in the delay-Doppler domain and (ii) signaling of information in the delay-Doppler domain. Both these aspects stand in sharp contrast with the conventional multicarrier communication paradigm where both channel representation and information signaling are carried out in the time-frequency domain. In this regard, OTFS constitutes a fundamental paradigm shift in communication theory, moving it away from traditional time-frequency (TF) signal processing to delay-Doppler (DD) signal processing.

The book covers various aspects of OTFS including a thorough discussion of its physical foundation and theoretical underpinnings as well as aspects of system design and algorithms. In this context, the book includes a comprehensive description of the underlying mathematical theory while emphasizing its structural connections to conventional modulation formats and drawing parallels between the Fourier theory of linear time-invariant systems and the more general Zak theory of linear time-varying systems.
