Inspired by the demands of sensing and communication in high-mobility scenarios such as
vehicle-to-everything (V2X), we propose an orthogonal time frequency space (OTFS) based …

Orthogonal Time Frequency Space (OTFS) modulation has recently been proposed for
communication in doubly selective channels. Together with millimeter waves, OTFS seems …

In orthogonal time frequency space (OTFS) systems, channel estimation (CE) is often
performed using a pilot based approach. This is usually done in two steps: first, valid …

This paper addresses the problem of delay-Doppler (DD) domain power allocation for
orthogonal time frequency space (OTFS)-based cognitive radio (CR) systems with the high …
