面向宽带传输的短波链路建立协议分析

HF Link Establishment Protocol for Wideband Transmission

简要描述了短波链路建立协议与传输波形的发展,并详细分析3G自动链路建立(3GALE)和北约4538快速链路建立(FLSU)机制的工作原理。为使短波宽带波形得到应用,在北约4538 FLSU机制的基础上,对链路建立协议进行修改,形成宽带快速链路建立(WB-FLSU)协议。建立网络仿真模型,对3G-ALE、北约4538 FLSU和WB-FLSU 3种链路建立协议进行链路建立时延、链路建立成功率和吞吐量等关键指标的仿真。仿真结果显示,面向宽带传输的WB-FLSU能够提高网络性能。根据分析结果提出了WB-FLSU的研究方向。

The development of high-frequency （HF） link establishment protocol and transmission wave- form is described, and the working principle of 3G Automatic Link Establish （3G-ALE） and the North Atlantic Treaty Organization （NATO） 4538 Fast Link Setup （FLSU） also analyzed in detail. In order to make full use of HF wideband （WB） waveform, the link establishment protocol is modified to form WB- FLSU based on NATA 4538 FLSU. The simulation model of network is established and the key factors of link establishment analyzed, such as time delay, success rate and throughput among 3G-ALE, NATO 4538 FLSU and WB-FLSU. Simulation results show that WB-FINU could improve the capability of network. This paper finally suggests the research direction for WB-FLSU.
