Abstract
A code-tracking system includes a loop filter, which receives an early/late error signal and outputs a loop filter error signal. An error scaling device receives the loop filter error representing an update and provides a code tracking adjustment signal. A controller monitors a frequency of updates and/or a number of same direction updates and provides a filter coefficient in accordance with the frequency of updates and/or the number of same direction updates.
