本文讨论一种中低速跳频通信FH-2FSK系统的同步方案,说明此系统中比特同步的建立与保持、跳频图案同步的建立与保持的原理,并着重分析其同步性能及如何使用微处理机控制上述工作。文中给出一种跳频通信同步的实验室模拟系统。对微处理机在系统中的应用、跳频通信传输数字电话及跳频系统同步的建立与保持进行的试验表明,此方案是可行的。
This article discusses a low-speed frequency hopping communication FH-2FSK system synchronization scheme to illustrate the system bit synchronization to establish and maintain the principle of the establishment and maintenance of frequency hopping pattern synchronization and focus on its synchronization performance and how to use micro-processing Machine control of the above work. In this paper, a laboratory simulation system for frequency hopping communication synchronization is given. Experiments on the application of microprocessors in the system, the establishment and maintenance of frequency hopping communication digital telephone and frequency hopping system synchronization show that this scheme is feasible.
