Scalable OTFS-Based Multi-LEO Downlink Access Using Doppler-Block Resource Allocation

Future non-terrestrial networks (NTNs) are expected to rely on dense low Earth orbit (LEO) satellite constellations capable of providing simultaneous coverage to a common user terminal. While Orthogonal Time Frequency Space (OTFS) modulation has emerged as a promising waveform for high-mobility satellite communications...
