Communication Interference Technology Research Based On The Multi-Node Collaboration And Coherent Synthesis

In recent years, with the development of electronic warfare technology, the research of accurate communication interference technology has become a hot. It is necessary to ensure our communication system operating normally, while on the other side, make electromagnetic interference to the specified area to reduce the correct transfer rate of the other’s communication. Communication interference technology plays an important role.On the researching of existing wireless communication interference and anti-jamming technology, the multi-carrier superimposed interference technology is introduced. On the use of CI principle and multi-carrier aggregation principle, the convergence of multi-frequency wavelet interference can be controlled by this study. The center aperture control algorithm is described and specific parameter settings, as well as the generation and analysis of simulation results. At the same time on the basis of single node aggregation of a multiple of frequency sub-waves, it is also extended to the situation of multiple nodes.5nodes are used in this simulation and the research of5nodes collaborative coherent interference signals is carried out. The100m aperture collaborative coherent signal,350m aperture synthesis interference signal and the500m aperture interference signal are simulated. The feasibility and effectiveness of the aperture control is illustrated.Some test scenes are designed according to the kind of communication signals. BPSK modulation of the other signal is interfered by the generating interference signals. The simulation aperture is100m,350m and500m. At the same time, to further verify the effect of the interference the QAM modulation signal is also conducted the same interference simulation.The research work of this paper is an important part of scientific innovation project and the project has passed the acceptance.
