Title:
METHOD FOR ESTIMATING ARRIVAL TIME OF WIRELESS COMMUNICATION SIGNAL AND COMPUTER-READABLE RECORDING MEDIUM RECORDING SAME
Document Type and Number:
WIPO Patent Application WO/2017/122855
Kind Code:
A1
Abstract:
A method for estimating an arrival time of a wireless communication signal comprises the steps of: receiving a packet including a first preamble, a second preamble, and a start of frame delimiter (SFD) by a receiver; estimating, by the receiver, a first delay time on the basis of a time point of demodulating the SFD and the symbol length of the first preamble; and estimating, by the receiver, a second delay time on the basis of an accumulated correlation degree calculated by performing an accumulated correlation calculation on the second preamble.
