Abstract
Circuit scale and power consumption of a base station is reduced with a feature of a sector-free configuration in routing processing. The feature is realized in a base station having transmitters corresponding to a plurality of sectors, as there are a switch distributing signals corresponding to a plurality of subcarriers to the plurality of sectors, respectively, and an inverse Fourier transform processor performing inverse Fourier transform processing on the signals for the plurality of sectors distributed by the switch, so as to supply to each corresponding transmitter among transmitters corresponding to the plurality of sectors.
