摘要
A Global Positioning System receiver (figs 1, 2A and 2B) includes an intermediate frequency (IF) processor configured to downconvert (105) broadcast signal to generate a first channel signal which is further downconverted to recover a PRN signal by an angle rotator (113). The receiver further includes a signal generator configured to generate N gated PRN signals (201A). The N gated PRN signals are generated based on a local replica PRN signal time-divided by M intervals within a chip period of the local replica PRN signal. N and M are positive integers. A number of correlators (205B) are also provided. Each of which the correlators are configured to multiply a respective one of N gated PRN signals with the PRN signal to generate a number of correlation values. The correlation values are utilized to monitor distortions in the broadcast signal and/or to track the carrier signal (211B). Further, a corresponding method is also provided.
