Abstract
A radio transmission apparatus that uses a plurality of band groups and that transmits a signal subjected to frequency hopping between a plurality of bands in each band group at a local frequency apart from the center frequency of each band includes a local frequency generating unit that generates a local frequency lower than the center frequency of each band in a first band group in the transmission with the first band group. The local frequency generating unit generates a local frequency higher than the center frequency of each band in a second band group in the transmission with the second band group, the local frequency to be generated being the same as the local frequency generated in the transmission with the first band group.
