时分多址(TDMA)扩频通信系统的同步捕获是一个很重要的问题,如何实现快速同步则更重要。采用声表面波器件,时间延时门和一致检测窗能十分满意地解决同步的快速捕获,精度达正负半个码元。本文还讨论了两种基本的快速同步捕获的方法,並给出了试验结果。 Time-division multiple access (TDMA) spread spectrum communication system synchronization capture is a very important issue, how to achieve rapid synchronization is more important. The use of surface acoustic wave devices, time delay gates and consistent detection windows can be very satisfied with the rapid capture of synchronization, accuracy of plus or minus half a symbol. This paper also discusses two basic methods of fast synchronization acquisition, and gives the test results.
