卫星舱内无线组网传输技术研究

卫星舱内无线组网通信具有多径干扰严重及电磁环境复杂等特点,本文设计了一个应用于星内的分布式Adhoc无线通信网络系统,重点阐述了无线节点组网、抗多径干扰及单机节点设计,对设计的星内无线通信系统的抗干扰和中继传输性能进行了仿真研究和测试验证。试验结果表明,所设计的无线通信网络能够满足星内多径环境下分布多跳式的组网传输需求,为航天器舱内无缆化信号传输奠定基础。

Design of Cabin Wireless Adhoc communicationsystem for satellite

Satellite cabin wireless network communication have the characteristic of multipath interference variety and complex electromagnetic environment. The paper discusses the application of distribulted Adhoc wireless communication system for special requirements of satellite cabin communication. The performance of the distribulted Adhoc system against Multipath Interference is analyzed, focuses on the design of wireless network nodes, anti-multipath scheme and facility node. the relay transmission in cabin wireless communication test is carried out. The experiments results show that this distribulted Adhoc cabin wireless communication system can meet the network requirements for Distributed Multi-Hop transmission in cabin Multipath Environment, laying the foundation for cableless cable transmission in spacecraft cabin.
