A Novel Wideband Transmission Technology of High Frequency

3G-ALE提高了短波通信系统的可通率和可靠性。随着应用的发展,现有短波传输技术很难满足可靠高速的通信要求,由此短波宽带传输技术成为研究热点之一。详细阐述了短波传输技术发展现状和发展趋势,引入一种新的宽带传输方式,并根据宽带传输特性改进3G-ALE建链方式,形成适合短波宽带传输的链路建立方法。这种短波宽带传输技术可以提高短波通信的可通率、缩短链路建立时间。

3G-ALE （Third Generation Automatic Link Establishment ） improves the available probability and reliability of HF （High-Frequency） communication system. With the development of applications, the current HF transmission technology is difficult to meet the requirements of high-rate and reliable communi- cation, thus HF wideband transmission technique becomes one of the research hotspots. In this paper, the current situation and development trend of HF transmission technology is expounded in detail. A new wide- band transmission mode is introduced, and 3 G-ALE link establishment method is improved in accordance with the characteristic of wideband transmission, therefore a link establishment method suitable to HF wideband transmission is formed. The HF wideband transmission technology could improve the available probability of HF communication and shorten the time for link establishment.
