Abstract

The invention discloses a multi-beam high-throughput satellite communication system based on MIMO and an implementation method thereof. The satellite system comprises a plurality of gateway stations,the gateway stations are bidirectionally connected to satellites through feeder line links, the satellites are bidirectionally connected to user terminals through user links, the information interaction path comprises that the gateway stations are transmitted to the user terminals through the satellites and the user terminals are transmitted to the gateway stations through the satellites, and thegateway stations are connected to a core network; feed multi-beam bands of a plurality of gateway stations are aggregated, the required bandwidth is increased by utilizing frequency multiplexing, high-throughput satellite communication is realized by utilizing a multipoint beam structure, and higher service flexibility is achieved.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, and in particular relates to a MIMO-based multi-beam high-throughput satellite communication system and an implementation method. Background technique [0002] With the rapid development of information technology and the increasing variety of information applications, people put forward higher and higher requirements for the communication quality and capacity of satellite communication systems, which directly promotes the development of satellite communication full coverage, large capacity and high bandwidth requirements. The satellite communication system consists of communication satellites, earth stations, management and control systems, etc. The earth stations are divided into fixed stations, mobile stations, or sea or air earth stations (such as ships, airplanes or trains), which can realize ubiquitous information transmission and message distribution. In the foreseeable fut...
