摘要/Abstract

摘要：

由于电离层信道具有不可摧毁性,在应急通信领域研究短波通信协议就显得尤为重要。文中在第三代短波自动链路协议基础上,采用新技术对多址接入技术进行了研究分析,并利用OPNET Modeler 14.5网络仿真平台验证方案的可行性。在短波通信网络模型中,管道机制利用长期信道预测软件VOACAP获取电离层信道质量参数进行无线信道建模;核心函数和C编程语言进行3G-ALE节点模型及相关进程模型、网络模型的建模。对不同场景进行的仿真实验表明,信道质量对网络节点间建链成功率影响最明显,网络节点个数及两节点间距离对建链成功率影响次之。

关键词: 短波通信, 多址接入, OPNET, VOACAP, 建链成功率

Abstract:

Because of the undestructibility of ionospheric channel, it is very important to study short-wave communication protocol in the field of emergency communication. Based on the third-generation short-wave automatic link protocol, this paper studies and analyzes the multi-access technology with the new technology. The feasibility of the scheme is verified using OPNET Modeler 14.5 network simulation platform. In the short-wave communication network model, the pipeline mechanism uses the long-term channel prediction software VOACAP to obtain the ionospheric channel quality parameters for wireless channel modeling. The core function and C programming language are adopted to establish the 3g-ale node model and the related process model and network model. Simulation experiments show that the channel quality has the most significant effect on the successful ratio of the chain between network nodes, and the number of network nodes and the distance between two nodes have the lower effect.

Key words: short-wave communication, multiple access, OPNET, VOACAP, successful ratio of link establishment
