Spread-Pilot-Aided Channel Estimation for Zak-OTFS-Based Multi-Satellite Cooperative Transmission
Multi-satellite cooperative transmission (MSCT) is a promising paradigm to enhance transmission performance in Low Earth Orbit constellations. Benefiting from the robustness against doubly-selective channels, orthogonal time frequency space (OTFS) modulation is suitable for such high-mobile MSCT scenarios. However, con...
