Two-Dimensional Power Allocation for OTFS-Based High-Mobility Cognitive Radio Networks

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-mobility secondary user (SU) reusing the spectrum of the low-mobility primary user (PU). A fundamental challenge for such an OTFS...
