Abstract
A wireless communication system includes a first communication device which arranges a frequency signal into which a single carrier signal is converted by time-to-frequency conversion in subcarriers and wirelessly transmits a resultant signal and a second communication device which receives the signal wirelessly transmitted by the first communication device. The wireless communication system includes a selection unit which calculates, for each determined selection candidate as a combination of a predetermined segment size and information indicating predetermined average transmission power, a value indicating reception quality in the second communication device upon transmission by the first communication device by using an arrangement using the predetermined segment size, and the predetermined average transmission power, and which selects a selection candidate to be used upon transmission by the first communication device from among the selection candidates based on the calculated value indicating the reception quality. Therefore, an excellent transmission efficiency is obtained.
