Design And Implemention Of Cognitive Radio Decision Naking Under High Spped Frequency Hopping

With the development of communication technology,people's demand for the quality of communication is more and more high.In some special circumstances,the communication frequency is disturbed and the communication system is paralyzed.At this point,how to find and bypass the interference,ensure reliable communication has become the focus of research.Cognitive radio technology has a strong spectrum sensing ability,can timely find and bypass the interference,improve the anti-interference ability of the system.Therefore,it is of high practical value to study how to use cogntive radio technology to find and bypass the interference.According to the needs of the cooperative units,we have completed the development of broadband software radio communication platform based on cognitive radio technology.The existing research work has been able to find and bypass the interference,to achieve reliable communication,has been affirmed by the cooperative unit.The system response time is longer,and the accuracy of spectrum decision-making needs to be improved.In order to further improve the performance of the communication platform,the project team proposed a broadband software radio communication platform based on cognitive radio technology,and the design and implementation of the decision is an important part of the improvement program.The main work and innovation of this paper are as follows:1.The design and implementation of a communication protocol for cognitive radio decision-making is presented.The scheme includes the design and implementation of the data exchange protocol between the physical layer and the application layer,the application layer and the application layer.2.The design and implementation of a cognitive radio decision-maker is presented.The scheme includes the data transmission module,the visual graphic interface display module,and the design and implementation of the data processing module3.A design scheme of cognitive radio decision-making machine is presented.The scheme includes the design and implementation of the network port receiving module and the frequency spectrum decision.4.The whole simulation test is carried out on the terminal system,and the test results are analyzed.Test results show that the scheme is reasonable and feasible,and can effectively reduce the system response time and improve the accuracy of the spectrum decision and improving the performance of the system.
