Channel Simulation Method of Multi-beam Flexible Forwarding Satellite

With the development of antenna technology and digital channelization technology, multi-beam and flexible forwarding have been widely used in satellite communications payloads. At the same time, it is a challenge to simulate the multi-beam flexible forwarding satellite channel. Based on digital channelization technology, this paper proposes a channel simulation method suitable for multi-beam flexible forwarding satellite communications system, which realizes the exchange of arbitrary multi-channel combinations. The simulation channel is verified to be real and effective through experiments, and can be used for the beam switching and networking application capability verification of the satellite mobile communications terminal, which can effectively improve the efficiency of its performance test and effectiveness evaluation.
