| Abstract: | 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. |
