摘　　要：通过分析L2C码的信号格式,对L2C码信号的产生和可变相关长度的窄相关器进行了研究,设计了L2C码产生器和可变相关长度的相关器,最后进行仿真,得出结论:该设计能够精确产生GPSL2C码,可变相关长度相关器能够提高接收机的定位精度和抗多径干扰能力。为设计采用L2C码的GPS接收机提供了参考。Based on analysis of the structure of L2C code,locally generated L2C code is designed,and we use the narrow correlator technology to improve the fact of measure error and eliminate the multipath error for L2C signal.Finally MODELSIM and QUARTUS were used to integrate and simulate the results.It provided a reference design for GPS receiver based on L2C code.
