摘要
对卫星通信中比较常用的多址接入方式进行了比较,提出了一种固定分配与自由分配相结合的卫星混合多址接入协议,对指标性能进行了分析。试验结果表明,该协议具有业务接入灵活、卫星频带利用率高、系统实现简单等特点,适用于高动态平台卫星通信。研究内容对相关工程应用具有一定的参考价值。
Basic multiple access techniques in satellite communication are compared. A hybrid satellite multiple access protocol based on Fix Allocation Multiple Access（FAMA） and Free Allocation（FA） is designed for satellite communication system, and specifications and performance are analyzed. Test result shows the proposed protocol is featured by easy accessing, efficient bandwidth utilization and it is applica- ble for high dynamic mobile platform satellite communication. The research in this papaer has reference value for engineering applications.
