Zak-OTFS: Pulse Shaping and the Tradeoff between Time/Bandwidth Expansion and Predictability
We also demonstrate that, by limiting DD domain aliasing, Gaussian filters extend the region where the crystallization condition is satisfied.
Zak-OTFS for Integration of Sensing and Communication
The self-ambiguity function of the point pulsone is supported on the period lattice ${\Lambda}_{p}$, and by applying a discrete chirp filter, we obtain a spread pulsone with a self-ambiguity function that is supported on a rotated lattice ${\Lambda^*}$.
OTFS -- Predictability in the Delay-Doppler Domain and its Value to Communication and Radar Sensing
This reconstruction formula makes it possible to study predictability of the Zak-OTFS I/O relation for a sampled system that operates under finite duration and bandwidth constraints.
OTFS -- A Mathematical Foundation for Communication and Radar Sensing in the Delay-Doppler Domain
Orthogonal time frequency space (OTFS) is a framework for communication and active sensing that processes signals in the delay-Doppler (DD) domain.
