Discussion on the Distributed Multi-Satellite Cooperative Transmission Technology for Multi-User Broadband Smartphones Directly Connected to LEO Satellites

In this paper, we propose a novel distributed multi- satellite cooperative transmission (DMCT) system model. Based on the analysis of the channel correlation between multiple antennas of multiple satellites and multiple antennas of a single smartphone in this model, we design three types of connection modes under different scenario configurations by drawing on terrestrial mature MIMO technologies. Then, we further discuss and analyze the application limitations and main characteristics of each connection mode. Finally, we discuss several key technologies that need to be conquered for the implementation of the proposed DMCT based system.
