Delay Doppler, Zac-OTFS, and Pulse Shaping Explained

This 30-minute video lecture explores Delay Doppler Digital Communications and Zac-OTFS (Orthogonal Time Frequency Space) modulation, along with pulse shaping techniques for time-domain implementations. Dive into the mathematical foundations of communication and radar sensing in the delay-Doppler domain using presentation slides developed jointly with Prof Stephen Hanly for his Keynote Talk at the 2025 Australian Communications Theory Workshop. Learn about the implementation of Zak-OTFS via time and frequency windowing, building upon concepts from previous videos about OFDM, subcarrier spacing, cyclic prefixes, and MIMO communications. The lecture references scholarly publications from IEEE Transactions on Communications and IEEE BITS Information Theory Magazine, providing a solid theoretical foundation for understanding these advanced digital communication concepts.
