Sinc and Gaussian-sinc filters yield narrower main lobes in Zak-OTFS self-ambiguity functions, improving resolvability for dense targets with peak-detection receivers while Gaussian excels in sparse scenes due to low sidelobes.

Zak-OTFS carriers, realized as pulsone waveforms, yield predictable non-selective I/O relations under bounded channel spreads due to their structure as common eigenvectors of the discrete Heisenberg-Weyl group, with similar structure shared by AFDM, OTSM and ODDM.

Zak-OTFS: A Predictable Physical Layer for Communications and Sensing
Zak-OTFS carriers, realized as pulsone waveforms, yield predictable non-selective I/O relations under bounded channel spreads due to their structure as common eigenvectors of the discrete Heisenberg-Weyl group, with similar structure shared by AFDM, OTSM and ODDM.
