Low-complexity Equalization of Zak-OTFS Via Neumann Series
Vineetha Yogesh, Saif Khan Mohammed, Sandesh Rao Mattu +2
We describe a general method for selecting an orthonormal basis of carrier waveforms that aligns the basis with delay / Doppler characteristics of a wireless channel. We show that…

A Hybrid I/O Relation Estimation Scheme for Zak-OTFS Receivers
Sai Pradeep Muppaneni, Vineetha Yogesh, A. Chockalingam
In this paper, we consider the problem of estimating the delay-Doppler (DD) domain input-output (I/O) relation in Zak-OTFS modulation, which is needed for signal detection. Two app…
