Disclosed is an apparatus and method for near field communication in an ultra wideband (UWB). An apparatus for near field communication in an UWB may include a determiner to determine the number of repetitions of a first sequence in each of n preambles, n denoting a natural number, and a processor to generate n short preambles by repeatedly arranging the first sequence based on the determined number of repetitions, and to generate the n preambles by arranging a long preamble with respect to each of the generated n short preambles.

A data transceiving apparatus and method in a centralized MAC-based wireless communication system are provided. The data transceiving method of a centralized MAC-based device may include: setting a direct path to a device and a relay path to a piconet coordinator (PNC); selecting any one of the direct path and the relay path; and transceiving data via the selected path.
摘要:
A data transmission system that transmits data in a wireless environment such as a wireless communication network is provided. The data transmission system includes an access point (AP) and a terminal. The AP transmits control information to the terminal, and the terminal selects a data period to transmit the data based on the control information. The terminal may determine an operation clock, a channel bandwidth, and the like according to a data transmission rate of the data to be transmitted. The terminal may operate at a low operation clock according to the data transmission rate, thereby reducing power consumption.

Methods for transmitting and receiving data of a station includes setting a direct route to a corresponding station and a relay route to a relay device, selecting one route as between the direct route and relay route, and transmitting and receiving data through the selected route. A non-transitory computer-readable storage medium may store a program including instructions to cause a computer to perform the method. The setting may be performed by a processor and the transmitting and receiving may be performed respectively by a transmitter and a receiver.

Provided herein is a sentence hiding and displaying system comprising: an image creating interface receiving an input of information on an original image, a plurality of sentences corresponding to the original image, and a language that needs to be hidden; an image creator configured to determine a sentence that needs to be hidden based on the plurality of sentences and the language that needs to be hidden, and to create on the original image an image where the sentence that needs to be hidden is hidden; a sentence display interface configured to receive an input of information on a language selected by a user; and a sentence extractor and displayer configured to parse a sentence expressed in the selected language of among sentences that need to be hidden based on the hidden image and the selected language, and to display the sentence expressed in the selected language.
摘要:
Provided are a method and apparatus for transceiving an asymmetric point-to-point moving signal and securing an uplink channel using a horizontal blanking interval (HBI) in which a video signal transceiving apparatus can combine a plurality of HBIs and a plurality of active lines (ALs) into a single section, and when auxiliary data exists in a corresponding HBI, can change an order of the HBI to the last and transmit map information including arrangement information to a video signal display apparatus, and the video signal display apparatus can receive the map information and analyze the received map information to thereby acquire an uplink channel using HBI excluding auxiliary data and transmit control signal data via the acquired uplink channel.
摘要:
A scheduling method of giving a chance for transmission to a plurality of terminals in the same time period, and a device therefor are provided. The scheduling method includes: transmitting first scheduling information to terminals in a network, the first scheduling information defining transmitting/receiving terminals and a transmission time period; receiving channel measurement information including inter-terminal interference information from the terminals in the network; and generating second scheduling information defining transmission time periods and a plurality of transmitting/receiving terminals that do not interfere with each other by using the channel measurement information.
摘要:
Disclosed are an Unequal Error Protection (UEP) apparatus and method thereof for transmitting various types of uncompressed video signals in a broadband high frequency wireless system. The UEP apparatus may include a UEP transmission controller to verify a bit separation point of separating a color depth and priority for each pixel element being composed of a video data pixel when video data is inputted, and to control an error correction coding of correcting relatively many errors to be used in information with a high priority for each pixel element, a bit separator to separate the video data pixel through a control of the UEP transmission controller based on the priority for each pixel element, and a channel coding unit to use a corresponding error correction coding through the control of the UEP transmission controller based on the priority for each pixel element.
