Research and FPGA Implementation of the Narrow-Correlator of GPS L2C Code

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.
