Abstract
A subcarrier allocation apparatus of the present invention includes: memory () that stores allocation patterns of links for allocation of subcarriers to the links; selector () that selects the subcarriers one by one in order; allocation evaluation value calculators () that are arranged in conjunction with cells of base stations and that calculate, for each allocation pattern, allocation evaluation values indicating desirability of allocation in the corresponding cells at the time of the allocation of the subcarrier currently selected by selector () to the links in accordance with the allocation pattern; adder () that adds, for each allocation pattern, the allocation evaluation values calculated by allocation evaluation value calculators (); and maximum value detector () that detects a maximum value from the addition result of the allocation evaluation values added by adder () and that determines the allocation pattern, in which the addition result indicates the maximum value, as an optimal allocation pattern of the subcarrier currently selected by selector ().
