Fast Acquisition of GPS Signal Using Extended Multiple Correlator based on FPGA

摘要：

This paper presents a detailed design of GPS signal fast acquisition system using the method of extended multiple correlator in FPGA. A 12-channel GPS signal acquisition system is implemented and an extra noise-monitoring channel is used to provide an adaptive threshold. Programming the system on FPGA development platform, results show that the system can acquire GPS signals faster than traditional receivers without great complexity. This design has high practical value, which can be directly used in GPS receiver, and also can extend its using in other direct sequence spreadspectrum receivers.
