| 摘 要： | 提出一种异步组网电台的实时分选方法，该方法仅仅利用各时刻的跳频信号载频信息即可将多个跳频电台分开，计算量少，能实时分选。方法还考虑了实际应用中跳频信号转换载频期间存在的空隙和由于信道衰落信号丢失产生的空隙，增加了分选鲁棒性。最后仿真了载频估计精度、组网电台数目、丢失数据率对分选性能的影响。方法在工程中得到了应用，效果良好。

| Abstract: | A new real-time sorting method for non-orthogonal frequency hopping signals is presented.Through comparing carrier frequencies of per sample time,multi-FH signals can be sorted one by one.In contrast with conventional techniques,the proposed method has a lower compute complexity,and can realize real-time sorting.In practical applications,there will have some intervals in carrier frequency switch period,otherwise,the channel fading also produce intervals.The method considered these intervals and became robus... |
