摘要
为了研究网络环境下战术数据链底层的建模与仿真方法,以QualNet仿真平台为例,对网络仿真环境下物理层、信道等底层相关的模型架构和信息流程进行了描述,对数据链底层建模及仿真中涉及的模型有限状态机、时延计算、无线传播预测、干扰信号功率计算、信号接收判断等5项关键技术进行了研究和分析,可为今后的相关仿真工作提供借鉴。
In order to research the modeling and simulation technique of tactical data link （TDL） in net- work environment, the model architecture and message flow of physical layer＆channel are described in QualNet simulator. The five key techniques of lower layer modeling are studied and analysed including model FSM（ Finite State Machine ）, delay computing, wireless propagation forecasting, power computing for interference signal and error checking for receiving signals . The content of this paper provides reference for future related simulation works.
