  • Publication number: 20140354262
    Abstract: A phase locked loop (PLL) lock detector may be configured to observe the phase error signal from a phase comparator of a PLL circuit. The PLL lock detector may accumulate a sum of phase errors and compare the sum of phase errors to determine whether the PLL circuit is locked in phase with the reference signal. Various modifications to the phase error signal and sum of phase errors may be used to improve the efficiency of the PLL lock detector. Configurable settings for the accumulator and a comparator may be used to adjust the operation of the PLL lock detector.

  • Patent number: 7746918
    Abstract: A bit synchronization method and system for a GPS, which receives a satellite signal sent by a satellite to accordingly produce a synchronous signal. Each data bit of the satellite signal consists of N CA-codes. A data buffer receives and stores the data bits of the satellite signal. A matched filter filters the N CA-codes of each data bit in order to compute correlations of the N CA-codes of each data bit, and accordingly output a correlation set corresponding to the data bit, wherein the correlation set has N correlations. A selector selects one with the greatest value from the N correlations and uses the CA-code corresponding to the one with the greatest value as the synchronization signal.
