An accessory according to an example embodiment may be for an electronic device including a first housing, a second housing, and a hinge cover connecting the first housing to the second housing, and may include a first cover to cover the first housing, a second cover to cover the second housing, a holder configured to receive a body part of a user to hold the electronic device, and a connector to connect the holder to the first cover and the second cover. The connector may be configured have a first shape in an unfolded state of the electronic device, and have a second shape different from the first shape in a folded state of the electronic device. At least a portion of the connector may be deformed in the second shape. Other embodiments are also possible.

Accessory and electronic device comprising the same

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.

Method of performing synchronization and frequency offset estimation based on simultaneous phase compensation of single training sequence and receiver performing the same

Various embodiments of the present invention relate to an electronic device having covers which may be coupled and an operating method thereof, the electronic device may include a housing; a first cover coupled with at least part of the housing, and comprising at least one first identification terminal; a second cover coupled with at least part of the first cover, and comprising at least one second identification terminal which is electrically connectable with the first identification terminal; and a processor. The processor may be configured to obtain at least one of first information related to the first cover or second information related to the second cover, identify at least one of a type of the first cover or a type of the second cover based on at least one of the first information or the second information, and perform a designated operation based on at least one of the type of the first cover or the type of the second cover. Other various embodiments are possible.

Electronic device for performing operation on basis of types of identified covers, and operating method therefor

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.

Wireless local area network system, method of transmitting distance information and measuring distance of wireless local area network system

A method of operating a wireless communication apparatus configured to support adaptive beamforming of a base station, the method including receiving a sounding packet from the base station through a plurality of sub-carriers, generating first channel information corresponding to first sub-carriers among the plurality of sub-carriers based on the sounding packet, performing an interpolation operation using the first channel information to generate second channel information corresponding to second sub-carriers among the plurality of sub-carriers, generating first beamforming feedback including the first channel information and the second channel information, and transmitting the first beamforming feedback to the base station.

Wireless communication apparatus for low-complexity beamforming feedback and method of operating the apparatus

A mobile terminal and a method of controlling the operation of the mobile terminal are provided. The method includes performing color sensing of a first color using a color sensor of the mobile terminal and recognizing a second color which corresponds to the first color; and providing an output based on the second color. The mobile terminal includes a main body; a color sensor configured to perform color sensing of a first color; a controller configured to recognize a second color which corresponds to the first color; and an output unit configured to provide an output that is based on the second color. Therefore, it is possible to change the color of the mobile terminal into a variety of colors by driving the lighting module in accordance with color data generated by the color sensor.
