  • Method for estimating arrival time of wireless communication signal and computer-readable recording medium recording same
    Patent number: 11109337
    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.
