Abstract
In a wireless communication system that performs a wireless communication by performing band division into a plurality of sub-spectra, a transmission device includes a band division unit and a transmission gain control unit configured to control a transmission gain of each of transmission signals of a plurality of sub-spectra for each sub-spectrum in accordance with information that is related to a power density of each sub-spectrum and fed back from a reception device so that the power density of each of reception signals of the plurality of sub-spectra on the reception device is uniform, and the reception device includes a reception power density detection unit configured to detect the power density of each of the plurality of sub-spectra to be received, a feedback unit configured to feed back information regarding the power density to the transmission device, and a band synthesis unit. Thus, it is possible to avoid deterioration of signal quality in hand division and synthesis transmission.
