In this paper, evolutionary algorithm is used to optimize the flicker function of band-limited Gaussian noise interference, which disturbs the convergence of adaptive algorithm based on LMS in GPS receiver, so that the average null depth of GPS receiver under equal power is lower, and better jamming effect is achieved. The simulation results show that the jamming algorithm in this paper has better jamming effect than the band-limited Gaussian noise jamming in different jamming quantity.
A simulation training system is designed, which uses HLA architecture to realize the coordinated operation of network simulation, hardware in the loop access and electromagnetic computing. The system uses the standardized virtual real access interface to make the communication equipment simulator share the equipment parameters and interactive data with the network simulation model. VRNET is used for network simulation and interacts with the electromagnetic calculation module to form a complex electromagnetic environment. The system can be used in communication simulation training, electromagnetic interference array analysis and other fields.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
