摘要： A method is provided for adjusting timing alignment in which a receiver generates a plurality of imbalanced correction codes (1310), and square waves both having the same frequency. The receiver mixes the imbalanced correction codes with the square waves to create a mixed signal (1320), and integrates the mixed signal over a correction code period to generate a signal power value (1330). The receiver adjusts a phase of the square wave in a first direction when the signal power value satisfies a first criterion (1340, 1350), and in a second direction when the signal power value satisfies a second criterion (1340, 1360). Each imbalanced correction code is symmetrical. And a total integrated value of one of the imbalanced correction codes over the correction code period is either above a first threshold, or below a second threshold, the first threshold being greater than or equal to the second threshold.

摘要： A tracking circuit (100) is provided for controlling a locally-generated clock. A receive channel (110) in the tracking circuit receives an incoming signal and a local clock, generates a local signal based on the local clock, and compares the local signal and the incoming signal to generate a data signal and an unfiltered phase error signal. A loop filter (120) filters the unfiltered phase error signal to provide a filtered phase error signal. A numerically controlled oscillator (140) generates a correction clock based on the filtered phase error signal. And a filter control circuit (160) provides one or more filter control signals to control operational parameters of the loop filter. The correction clock is provided to the receive channel to modify at least one of the phase and frequency of the local clock. In addition, a sample switch (125) may also be provided to sample the unfiltered phase error signal.

摘要： A system (600) and method (500) are presented for mitigating a transient in processing a received signal (710) in a signal path associated with an Ultra Wideband (UWB) receiver. An impending processing event associated with processing the received signal is detected. A processing element (201, 202, 203, 204) capable of generating a transient when activated, is activated prior to the processing event such that the transient is mitigated or cleared when the processing event occurs and the received signal is processed. At least a portion of the processing element is normally deactivated so as to conserve power. The processing event includes one or more of: an acquisition processing event, a lock processing event, and a tracking processing event associated with the received signal in the signal path.
