Claim 0:
1. A wireless communication system that performs a wireless communication by performing band division of a spectrum of a transmission signal into a plurality of sub-spectra, the wireless communication system comprising a transmission device and a reception device, wherein
the transmission device includes:
a band division unit configured to perform the band division of the transmission signal into the plurality of sub-spectra; and
a transmission gain control unit configured to control a transmission gain of each of a plurality of the transmission signals of the plurality of sub-spectra for each of the plurality of sub-spectra in accordance with information that is related to a power density of each of the plurality of sub-spectra and fed back from the reception device so that the power density of a reception signal of each of the plurality of sub-spectra on the reception device is uniform,

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 from the transmission device;
a feedback unit configured to feed back to the transmission device the information regarding the power density of each of the plurality of sub-spectra; and
a band synthesis unit configured to perform band synthesis of a plurality of the reception signals of the plurality of sub-spectra, and

the information regarding the power density of each of the plurality of sub-spectra corresponds to one of:
an average value of the power density of each of the plurality of sub-spectra; and
reception power of a center frequency of each of the plurality of the reception signals of each of the plurality of sub-spectra.
