Research On Modeling And Simulation Technology Of Communication Data Link

With the rapid development of wireless communication technology,data link research in all aspects have made rapid development.Data link with high transmission efficiency,anti-interference ability,good confidentiality characteristics,in order to meet the mission requirements of modern combat,the data chain is widely used in the military field.At the same time,the increasing complexity of the communication system makes the research and design of the system cost of the system correspondingly improved.In order to study the communication system better,it is necessary to establish an effective system evaluation model and design a reasonable evaluation method.The research on the communication system modeling and simulation technology can deepen the understanding of the principle of the communication system.Whether it is to improve the existing system or design a new system,have important reference value and guiding significance.In this thesis,the development of airborne data link communication system performance evaluation simulation software as the goal,for the communication data link system in-depth study of its modeling and simulation technology.On the basis of studying the function of each module of communication data link system and its simulation model,the corresponding performance evaluation model of communication data link system is established.Then,from the point of view of software development,the design of data link simulation software is completed according to the simulation model of each module and the method of performance evaluation of communication data link system.Finally,the code is implemented according to the software design.This thesis mainly from the following three parts to carry out research work:(1)Understand the basic working principle of the data link system from the technical model and the simulation model of the communication data link system,and then comb the function and simulation model of the module and make the corresponding simulation work respectively.(2)In order to study the operational effectiveness evaluation model of airborne data link communication system,the corresponding communication data link system performance is established according to the requirement of airborne system performance evaluation,which is the most important indicator of the performance of digital communication system,which provides a meaningful reference for the optimization of the airborne data link system.(3)According to the working principle and simulation model of the system submodule,combined with the method of performance evaluation of communication data link system,the communication data link simulation software is designed and realized by computer language,and it is used to evaluate the performance of communication data link system.
