In order to achieve digital chaotic PN sequence,this paper proposes a type of digital technology for continuous system.Firstly,the continuous chaotic system is converted into discrete chaotic system,and then on the platform of SIMULINK,the model of discrete chaotic system is constructed by using the module of DSPBUILDER.Through the simulation in MATLAB and QUARTUSⅡ,the design is confirmed to be feasible.Finally,the HDL file is downloaded into the FPGA,and the digital chaotic PN sequence is observed in the experimental setup.By using the D/A chip,the type of digital technology is confirmed to be accurate.
