摘　　要：论述在GPS接收机三个功能模块中基带信号处理模块的具体作用。利用FPGA技术的先进性和软件无线电技术的灵活性开发出具有自主知识产权的功能模块。介绍其设计实现,着重于伪码生成器和NCO的实现,同时给出相关的仿真结果。This paper presents the particular functions of base band signal processing module in the totally three processing modules of GPS receiver.The function module with independent intellectual property rights is developed base on both the advance of FPGA and the flexibility of software radio.This paper introduces its implementation,emphasizing on the PRN code generator and NCO,also,gives the corresponding simulation result.This success is a breakthrough on GPS core chip design,and makes it possible to realize the goal to independently develop the GPS receiver gradually.
