摘要
短波信道质量评估设备按技术体制分为两大类,分别是独立信道探测系统和嵌入式探测系统。介绍了两类系统的基本原理、目前研究和应用现状以及存在的问题,指出应将两类技术进行结合,根据通信业务进行针对性的信道分析以提高评估效率。最后对其发展方向进行展望,以期为短波实时信道估值方面的研究提供参考。
High frequency（HF） channel quality estimation equipment can be divided into two categories according to the technical system,one is independent sounding system and the other is embedded estimation system.This paper introduces the basic principles,research and application situation,and current shortages of two categories of channel estimation systems,and points out that the two kinds of techniques should be combined and channel analysis should base on service in order to improve efficiency.Finally,it provides the development prospects of the technique.It is hoped that all of this can provide a reference for research on real time channel evaluation for HF communications.
