短波网动态频率管理系统的状态查询设计

A method of link status inquiry for HF network dynamic frequency management

链路状态是进行短波网动态频率管理的重要依据,实时状态查询是获取链路状态的有效途径.提出了一种高效的、无需增加硬件资源的短波网链路状态查询机制,并设计了状态查询调度算法和空中接口波形.仿真对比了查询代价和收益,验证了该设计思路可以在对通信业务无明显影响的前提下,实现链路状态的收集.

In HF network, link status is an important parameter for dynamic fre- quency management. Real-time status inquiry is the optimal method for getting link status. This paper introduces an efficient method of HF network link status inquiry, designs the inquiry algorithm and burst waveform which can implement without additional hardware resources. Simulation results show that this method can get all link status data with negligible influence on communication.
