Analysis And Realization Of The Anti-jamming Communication Simulation Platform Based On Feature Parameter Extraction

As is known, information warfare has long become an important part of modern war. How to master the power of “information control” has become a major research project in military telecommunication domain. The battlefield situation is getting increasingly complex, and the various military communication high-tech are becoming mature, which in turn intensify the battle over information control. The modern war has already become an integrated warfare of army, navy and air force in the informationalized situation, and the efficient and reliable communication technologies play major role in winning. The interference methods and types of the enemy’s military wireless communication are also developing. In order to combat the contentiously changing interference, various anti-interference methods are developed. Various methods of spread spectrum, non-spread spectrum, time domain, frequency domain and power domain are employed to combat the interference due to their difference anti-interference mechanism. However, the enemy’s interferences are changing from fixed one to dynamic ones and from suppressing to flexible, among which dynamic interference poses the most hazardous threat. To slove the challenge, the traditional method is to change some features of signal sending to combat the interference. If one can know some features of the interference signal parameters, one can focus on these features to avoid the interference, which can be very effective.For now, there are various forms of interference, and also various anti-interference measures accordingly. Some researchers carry out simulation experiments of these anti-interference methods, especially the accuracy of the scanned features of the dynamic signal and the result of the anti-interference based on these parameters. However, these experiments are separated, and thus makes it hard for users to compare the effect of different methods. Therefore, if one can take the anti-interference methods, accuracy of the scanned parameters and the effect into a comprehensive experiment, and develop an anti-interference experiment integration base, it would be of great significance.First of all, the thesis concisely analyzes the background, purpose and significance of the research, and discusses the main contents of the anti-interference simulation experiment base together with the research thoughts and methods.Then, to meet the development requirement of the anti-interference base, the author analyzes the interference signal model and its mathematical expression. What’s more, the authors also analyzes the major algorithm of scanning the signal parameters, the theories of the communication anti-interference, regular algorithm of anti-interference and other concerning problems to provide a theoretical base of the development of the simulation base.After that, the author introduces the Matlab, a simulation software, and make a summary and analysis of the requirements of the anti-interference base. After offering the basic structure and the main contents and objects to be designed, the author programs the basic communication simulation program and interference and anti-inference programs. After the modulation and tests of the various simulation programs, the author develops the simulation base interface. Taking advantage of the simulation result of the interference, the author analyzes the result.
