Abstract:
A method for assigning a second finger in a Code Division Multiple Access (CDMA) wireless receiver wherein:(a) the method includes the steps of: (1) determining a gap between the assigned offset of a first finger and the offset of an energy peak detected by a searcher; and (2) assigning a second finger if the gap exceeds a first threshold; and (b) the method is characterized in that the method further includes the steps of: (1) slowing down the speed of a Time Tracking Loop for the first finger and a Time Tracking Loop for the second finger if the gap exceeds the first threshold but does not exceed a second threshold, which is greater than the first threshold; and (2) maintaining the speed of the Time Tracking Loops for both the first finger and the second finger if the gap exceeds the second threshold.
