| Περιγραφή: | This paper explores multi-satellite transmission schemes. The focus is on the multi-user downlink scenario, where two low Earth orbit satellites transmit data cooperatively, which are then combined at each of the ground user terminals. A single synchronization circuit is employed at the receiver to reduce the terminal burden. The orthogonal time and frequency space (OTFS) waveform is utilized to handle the residual offsets and schedule users on non-overlapping delay-Doppler resources. The paper leverages on OTFS, beam-centric compensation and the characteristics of the satellite channel to eliminate inter-user interference. Numerical results assess the effectiveness of the proposed scheme and highlight the improvement in performance achieved through satellite cooperation as compared to single satellite transmission.
