针对传输话音业务的小型VSAT网络系统，提出了一种基于FDMA/SCPC的无主站自组网方法。在该方法中，网内各站点能力相同、全网状连接，共享业务信道频率资源。站点通过扫描业务信道获取频点实时忙闲信息。当需要通信时，站点通过自发自收测试占用空闲信道，并发起通信申请。介绍了这种自组网方法的网络构成、频率配置和通信过程，并通过Matlab仿真对网络的呼损率、信道利用率等性能指标进行了分析。

Aiming at the small VSAT network system for voice-transmission service,a new self-organizing network based on FDMA/SCPC is proposed. In this method, every site is almost equal in capacity, the network in full mesh connection, and the frequency resource of business channel shared by all sites. Each site acquires the real-time information of frequency points through scanning business channel. When com-munication is required, the site occupies the idle channel by a self- sending and self-receiving test and launches a communication application. The network structure, frequency allocation, and communication process of the self-organizing network are described, and performance index of the network, including call-loss rate, channel utilization, is also analyzed through Matlab simulation.
