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.
