| titleOfInvention | Deep space downlink multi-hop transmission method and system based on GEO backbone relay |
| abstract | The invention discloses a deep space downlink multi-hop transmission method and a system based on GEO backbone relay, wherein an established spatial channel model is divided into two hops: the first hop is a space direct-view link of a deep space exploration node-GEO backbone relay, and a Rice channel is adopted for modeling; the second hop is the near-earth direct-view link of the GEO backbone relay-ground station, modeled with a shaded rice channel. Meanwhile, when a direct-view link exists between the deep space exploration node and the ground station, shadow Rice channel modeling is also adopted. According to the invention, perturbation influence among stars is deduced, and for the antenna performance influence of the GEO backbone relay node, calculation expressions of an interruption probability (OP) and an average symbol error probability (ASER) are deduced, so that the transmission performance of a downlink can be better analyzed. |
