Abstract: A method of performing synchronization and frequency offset estimation for an input signal includes receiving an input signal through a wireless channel, and performing a frequency compensation operation on the input signal based on a reference signal to generate a compensated input signal. The reference signal corresponds to an access code associated with the input signal. The method includes determining a synchronization timing and a frequency offset for the input signal by comparing the reference signal with the compensated input signal.

Abstract: A method of detecting synchronization timing and sub-band, includes: receiving an input signal corresponding to a training sequence; generating a template signal based on the input signal and a single reference signal; performing a matched filtering operation on the input signal based on the template signal; obtaining an adaptive threshold for detecting a target sub-band based on a result of the matched filtering operation; obtaining a peak tone for the target sub-band based on the result of the matched filtering operation; and determining whether the input signal corresponds to the target sub-band and a synchronization timing for the input signal based on the adaptive threshold and the peak tone.

Abstract: A wiring structure includes an etch stop film disposed on a substrate. A first insulating film is disposed on the etch stop film. A first wiring layer extends in a vertical direction perpendicular to an upper surface of the substrate and extends through the first insulating film and the etch stop film. A sidewall of the first wiring layer forms a first inclination angle of about 88 degrees to about 90 degrees with respect to a first horizontal direction parallel to the upper surface of the substrate. A surface of the first insulating film and a surface of the etch stop film in direct contact with the first wiring layer have a carbon (C) concentration less than or equal to about 3 at %.

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.
