Abstract: The present disclosure includes a method of performing synchronization and frequency offset estimation The method includes an input signal corresponding to a single received training sequence. Phase information and a phase index are generated by performing an auto-correlation function (ACF) on the input signal. A templet signal associated with a sample index of the input signal is generated based on at least one pre-stored look-up table (LUT), the phase index, a frequency bandwidth of the input signal, and the sample index. Power associated with the sample index is calculated by performing a matched filtering on the input signal based on the templet signal. A synchronization timing and a frequency offset for the input signal are simultaneously determined based on a result of the matched filtering.

Abstract: Disclosed is a method of transmitting a message for measuring a distance between a first terminal and a second terminal that are positioned in a basic service set (BSS), and in this case, the first terminal transmits a fine timing measurement (FTM) request frame for beginning of measurement of a distance to second terminal. The first terminal receives an Ack frame for the FTM request frame from the second terminal. The first terminal transmits a first data frame to the second terminal, by the first terminal. The first terminal receives a first Ack frame for the first data frame from the second terminal, by the first terminal. The first terminal transmits a second data frame but not the FTM frame to the second terminal. The first terminal receives a second Ack frame for the second data frame from the second terminal.
