Disclosed herein are a digital signage system for limiting a luminance range settable by a user according to the number of power supply units (PSUs) and a method of operating the same. The digital signage system includes a panel configured to display an image, a plurality of light emitting diode (LED) driver modules configured to provide to the panel, a display device including at least one power supply unit configured to supply power to the panel and the plurality of LED driver modules, and a system controller configured to control the display device. The system controller includes a display configured to display a luminance setting screen for controlling luminance of the image and a controller configured to change a settable maximum luminance value according to the number of power supply units when the luminance setting screen is displayed.

Digital signage system and operating method therefor

A method for estimating a self-interference channel by a communication device which operates in a full-duplex mode can comprise the steps of: determining the amount of resources to be used for estimating a self-interference channel for each antenna; transmitting a reference signal by means of resources distinguished by means of each antenna in accordance with the amount of resources that has been determined for each antenna; and estimating the self-interference channel on the basis of the reference signal.

Method for estimating self-interference channel and device for same

A method for estimating a self-interference channel by a communication device which operates in a full-duplex mode can comprise the steps of: transmitting a reference signal in a first transmission unit by means of resource elements (REs) of which the number is smaller than the number of antennas of a communication device; estimating a self-interference channel by using a first reference signal matrix, which is returned by means of a self-interference channel in the first transmission unit, and reference signal matrices which are returned by means of a self-interference channel in a predetermined number of transmission units prior to the first transmission unit; and storing information about the estimated self-interference channel.

The present disclosure relates to a method for storage or transportation of graphene oxide. The method for storage or transportation of graphene oxide comprises the steps of: carrying out wet spinning of a graphene oxide spinning solution to a coagulating bath to obtain graphene oxide pellets; drying the obtained graphene oxide pellets; storing or transporting the dried graphene oxide pellets; and redispersing the stored or transported graphene oxide pellets.

Method for storage or transportation of graphene oxide
