ABSTRACT:
An apparatus for synchronizing the reception of a spread-spectrum signal includes a synchronization apparatus having a code-matched filter, a running average unit coupled to the filter, a peak detector coupled to the running average unit, and a synchronizer coupled to the peak detector for providing an index of a peak. A corresponding method includes receiving a spread-spectrum signal having a period comprising a plurality of indexable samples, maintaining a mean array comprising a running mean value for each indexable sample over a variable number of periods, detecting a peak value of the array, calculating an average value of the array, computing a peak-to-average ratio in accordance with the detected peak value and the calculated average value, comparing the peak-to-average ratio against a time-varying threshold, and synchronizing the received signal when the peak-to-average ratio exceeds the current value of the threshold.
