Delay-Doppler Pulse Shaping in Zak-OTFS Using Hermite Basis Functions
Fathima Jesbin, Ananthanarayanan Chockalingam
The performance of Zak-OTFS modulation is critically dependent on the choice of the delay-Doppler (DD) domain pulse shaping filter. The design of pulses for is co…

A Gaussian-Sinc Pulse Shaping Filter for Zak-OTFS
Arpan Das, Fathima Jesbin, Ananthanarayanan Chockalingam
The choice of delay-Doppler domain (DD) pulse shaping filter plays an important role in determining the performance of Zak-OTFS. Sinc filter has good main lobe characteristics (wit…
