Abstract
The present invention provides a double delay-locked loop(DDLL) code tracking loop for spreading a linear section of an energy detecting area of the tracking loop by using several code time, and provides a delay-locked loop code tracking system for a receiver of a code spread communication system capable of performing an effective code tracking even when a changing ratio of a receiving path is large, by variably using a difference of a preceding time code and a delayed time code according to a change of a receiving environment being changed without cease. Accordingly, the code tracking loop of the present invention improves the receiver performance of the code spread radio communication system, and simplifies a structure of the receiver.
