IEEE 1588 PTP를 이용한 전파 지연 거리 측정의 정밀도 향상 기법 = Precision Improvement Technique of Propagation Delay Distance Measurement Using IEEE 1588 PTP

다국어 초록 (Multilingual Abstract)

IEEE 1588 PTP is a precision time protocol in which two systems synchronize without the aid of GPS by exchanging packets including transmission/reception time information. In the time synchronization process, the propagation delay time can be calculated and the distance between the two systems can be measured using this. In this paper, we proposed a method to improve the distance measurement precision less than the modulation symbol period using the timing error information extracted from the preamble of the received packet. Computer simulations show that the distance measurement precision is proportional to the length of the preamble PN sequence and the signal-to-noise ratio.
