Design And Implementation Of Part Of Broadband Fh Synchronous Communication System Based On FPGA

With the development of modern military communication technology,wartime equipment is not limited to weapons,materials,manpower etc.,but communication equipment also being received more and more attentions.As increasingly rapid development of wartime communication technology,information exchange between various military communication equipment becomes more and more complicated and the spectrum resource has been increasingly crowed.Moreover,communication-jamming technology in wartime communication presents a greater challenge.For these reasons,the US military developed Link16 data link in the 1980s,and its application of frequency hopping synchronization technology in wartime communications provides strong anti-jamming and security.In the domestic,with introduction of the concept of data link,the army and many laboratories provide a good theoretical basis for researches on data link.The laboratory of this thesis proposes a Link 16 overall framework,and implements a communication transceiver with high-speed hopping capability.And the author is responsible for the design and implementation of the FPGA portion of the framework.Firstly,this thesis introduces the current development of Link 16 in domestic and foreign,and provides a Link16 overall framework.Then,this thesis outlines some key technologies and presents the corresponding implementation difficulties.Secondly,this thesis proposes a model with a high-speed hopping synchronization capabilities,and designs hopping module and synchronization module of this model respectively.For synchronization module,four correlation method is proposed which applies the conventional frame synchronization to Linkl6 framework,and it's an improved model.Finally,according to the design of the framework,this thesis provides the implementation of FPGA portion.Based on modular solution,this thesis simulates each modular using ModelSim,and validates the design on a real Xilinx FPGA platform.
