CODE TRACKING APPARATUS FOR REMOVING MULTIPATH ERROR AND CODE TRACKING METHOD USING SAME

摘要

The present invention relates to a code tracking apparatus for removing a multipath error, which fixes the time difference between an early correlator and a late correlator at 1 to 2 chips and tracks the minimum point of the difference of output values of the correlators, to thereby improve the accuracy, tracking speed, and tracking area of code phase tracking even in cases where a variety of multipath interference signals, which cause position estimation errors, exists. The present invention also relates to a code tracking method using the apparatus.
