本文认为现代高频通信的特征在于充分开拓高频媒质的长处,尽量减少高频媒质的弱点对通信的影响。因此本文首先从总结高频媒质的优缺点开始,根据 HF 通信多维最佳化和通信窗口的概念,指出了提高高频通信质量的途径,即最大程度地扩展通信窗口的尺寸而使通信窗口和干扰窗口完全重合的可能性达到最小。特别指出了达到上述目的所采用的实时信道估值(RTCE)技术,可在很大程度上在整个通信时间内,找到不与干扰窗口全部重合的通信窗口。文中用较大篇幅介绍了近年来各国生产的采用 RTCE 技术的现代高频自适应通信系统,着重介绍了这些系统的特点及作者建议的使用场合。最后本文仍从高频媒质多维最佳化的观点出发,提出了未来高频通信的结构。为了更有效地使用高频媒质,未来的高频通信系统将是一种采用 RTCE 技术、全自动控制、具有高可靠 EOW 的自适应突发系统。为了有效地利用偶发 E 层传播和利用流星余迹,应展宽使用的波段,未来的高频自适应突发通信系统的波段复盖,应包括 HF 和流星余迹通信所使用的波段。 This paper argues that modern high-frequency communications are characterized by the full exploitation of the strengths of high-frequency media and the minimization of the impact of high-frequency media weaknesses on communications. Therefore, this paper first summarizes the advantages and disadvantages of high-frequency media, according to HF communication multi-dimensional optimization and the concept of communication window, pointed out ways to improve the quality of high-frequency communications, that is, to maximize the size of the communication window and communication windows and The possibility of complete overlap of interference windows is minimized. In particular, the Real-Time Channel Estimation (RTCE) technique used to achieve this objective is found, to a large extent, to find communication windows that do not overlap with the interference window to a large extent over the entire communication time. In this paper, the modern high-frequency adaptive communication system using RTCE technology produced by various countries in recent years is introduced with a larger space, and the characteristics of these systems and the recommended use of the author are introduced. Finally, this article still from the perspective of multi-dimensional high-frequency media optimization, proposed the future structure of high-frequency communications. In order to use high-frequency media more effectively, the future high-frequency communication system will be an adaptive burst system using RTCE technology, fully automatic control, and highly reliable EOW. In order to utilize the meteor shower trail effectively by sporadic E-layer propagation, the bands used for broadening should be broadened, and the band coverage for future high-frequency adaptive burst communication systems should include the bands used for HF and meteor-burst communications.
