摘　　要：综合考虑了GPS接收机的内部结构、工作原理和相关器设计参数,采用电子设计自动化设计方法,设计了基于现场可编程阵列的GPS接收机基带处理电路,电路采用VHDL语言实现并在QUATUSⅡ上进行了时序仿真。仿真结果和实际测试表明,电路工作正常,在软件的控制下可以对GPS基带信号进行处理,且性能可靠,具有很高的应用价值。最后,对于GPS现代化的BOC调制技术进行了分析。To address the problem ofa GPS receiver＇s intemal structure, working principle and the correlator design parameters. Electronic design automation design method based on field programmable gate array of GPS receiver baseband circuit. Circuit using VHDL language and QUATUS II on the timing simulation, the simulation results and actual test that the circuit works under the control of the software GPS baseband signal can be processed, and the performances are reliability and have very high appliances. Finally, GPS modernization of BOC （binary offset carrier ） modulation is analyzed.
