    • 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.
    • 目的:提供一种用于建立导频子载波的方法和装置,以减少在IEEE 802.16m中使用的导频用户的数量,从而准确地估计信道。 构成:选择单元(100)选择特定范围内的导频子载波的功率可变候选。 基于非线性函数,计算单元(200)计算功率变量候选中的导频子载波的特定数量。 根据提取的导频子载波的设定规则,去除单元(300)去除预定的子载波。 基于除去单元的结果之外的除了副载波之外的最终子载波的位置值,由此配置值包括天线。
