Abstract
An apparatus for setting a pilot subcarrier in an antenna selects candidates of power value variables of a pilot subcarrier existing within a predetermined range, and calculates and extracts pilot subcarriers of a predetermined number on the basis of a nonlinear function among the candidates of the selected power value variables. Next, the apparatus removes pilot subcarriers of a predetermined number from the extracted pilot subcarriers of a predetermined number in accordance with a rule and configures the antenna on the basis of position values of final pilot subcarriers except for a virtual subcarrier among the removal result. Further, the apparatus configures the antenna on the basis of the power value by determining the sum total of the power values corresponding to the position values of the final pilot subcarriers to correspond to the number of pilot subcarriers.
