Pseudo - Code Phase Modulation Fuze Signal Processing Technology Based On

With the progress of time, the radio fuze technology change rapidly.Continuous-wave pseudo-random code phase modulation technique is one of the popular radio fuze technology, the field-programmable gate array (FPGA) technology is gradually into the radio fuze design. Due to speed quickly, resources and high integration and erasable characteristics, FPGA technology stands out in the radio fuze. In this issue, the FPGA technology is applied to the continuous wave Pseudo Code Phase Modulation Fuze, the primary task and contribution of this issue are as below:(1) This issue is based on continuous-wave pseudo-random code phase modulation signal processing technology theory. First of all, Deep understanding of the parameters and formulas overall signal processing system, Then follow the requirements of the subject, combined with fuse theory, Overall a reasonable set of system parameters. Then using MATLAB-simulink process simulation design theoretically. Analysis of the similarities and differences between the signal processing results under different circumstances from the actual signal.(2) According to the simulation results of the theoretical part and parameters, this issue designs continuous-wave pseudo-random code phase modulation signal processing part using Verilog HDL hardware language. According to the original input signal, and rational planning the entire signal processing system implemented steps and processes to determine the implementation, optimization of FPGA design.(3) In accordance with the requirements of the system and on the recommendation of my opening report, this paper developes the proper PCB design solution. Then this issue summarizes the results of the various parts of the design, also optimizes the available parts overall. Last but not least, improvement plan is putted forward addressing the inadequate parts of my design.
