Abstract: PURPOSE: A method and a device for establishing a pilot subcarrier are provided to reduce the number of pilot subscriber which is used in IEEE 802.16m, thereby estimating a channel accurately. CONSTITUTION: A selection unit(100) selects a power variable candidates of a pilot subcarrier within a specific range. Based on a non-linear function, a calculation unit(200) calculates specific number of pilot subcarrier among the power variable candidates. According to the set rule of the extracted pilot subcarrier, a removing unit(300) removes the predetermined subcarrier. Based on location value of final subcarrier except virtual subcarrier among the result of removing unit, thereby configuration value comprised an antenna.

Abstract: PURPOSE: A communication quality information providing apparatus and method thereof are provided to visually offer real-time communication quality for a measurement location by interlocking with geographical information. CONSTITUTION: An image capturing unit(130) captures images according to a correcting command. The image capturing unit acquires image information. The image capturing unit maps the image information on geographical information corresponding to the image information. The image capturing unit creates image geographical information. A visualization apparatus(140) synchronizes communication quality information with location information or the image geographical information. The visualization apparatus creates communication quality visualization information.
