摘要
TDMA系统具有不存在交调干扰、卫星转发器工作效率高等优点。现提出一种基于单频TDMA方式卫星通信网络自组网方法,可适用在站点数较少且需传输语音、视频等多类业务的小型网络中。由于不设中心站,此系统建设周期较短,费用也较低,且具有较强的抗毁性。参考信息由各站点发出,当需要通信时,各站点通过自发自收方式占用时隙,发起通信,整个过程灵活、快速、简便。这里详细介绍这种方法的帧结构以及通信过程,为特殊情况下的无中心组网提供了参考。
The TDMA system has the advantage of no intermodulation interference and high efficiency of the satellite transponder.The self-organization method based on single-frequency TDMA satellite communication network is proposed, which can be applied to small networks with less sites and necessary to transmit voice and video services. For no establishment of central station, this system is short in construction period and low in cost, and fairly strong in resistance to destruction. The reference information is sent out by each site, and when the communication is in need, each site initiates communication via self-sending/receiving tests, and the whole process is flexible, fast and simple. This paper describes in detail the frame structure and the communication process of the proposed method, thus to provide a reference for the non-centre networking under special circumstances.
