METHOD FOR ACCURACY IMPROVEMENT OF TIME MEASUREMENT AND POSITION TRACKING APPARATUS USING THE SAME

摘要

Disclosed is a method for improving accuracy of time measurement and a position tracking apparatus using the same. A method for improving accuracy of time measurement includes receiving a radio communication signal and obtaining timing information in a received signal; tracking a code that detects inconsistent timing between the received signal and a tracking signal generated for the received signal; storing history information on the inconsistent timing between the received signal and the tracking signal for each bit of the received signal; and arithmetically averaging the history information and updating the timing information of the received signal with the arithmetically averaged value.
