摘要： A wireless communication system includes: wireless transmission devices; and a wireless reception device. Each of the wireless transmission devices is configured to transmit data by transforming a time domain signal into frequency domain signals to obtain first frequency signals, clipping a part of the first frequency signals to generate second frequency signals, and allocating the second frequency signals onto subcarriers. The wireless reception device is configured to demodulate, from signals received, time domain data transmitted. Communication is performed using a clipping rate set for each of the wireless transmission devices, the clipping rate being the number of the second frequency signals divided by the number of the first frequency signals.

摘要： 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.
