    摘要: A wireless transmission device converts signals having been subjected to a first modulation into frequency domain signals, and allocates the frequency domain signals converted to subcarriers for transmission. The wireless transmission device includes: a controller that selects, based on channel qualities of the subcarriers to which the frequency domain signals are allocated, a value satisfying a predetermined communication quality as control information indicative of the number of frequency domain signals included in each of segments into which the frequency domain signals are segmentalized; and an allocating unit that segmentalizes the frequency domain signals into segments, each of the segments including the same number of frequency domain signals as the value selected as the control information by the controller, and allocates the frequency domain signals included in each of the segments to sequential subcarriers.
