Abstract:
1. A wireless communication apparatus that transmits data to a counter apparatus by using a plurality of frequencies, the wireless communication apparatus comprising: a plurality of transmitting units that transmit the data corresponding to the frequencies; a distributing unit that distributes the data to be transmitted to the counter apparatus into the transmitting units; and a transmission-timing controlling unit that causes timings of transmitting frames from the transmitting units to match each other for every predetermined cycle, the frames each formed of the data distributed by the distributing unit, wherein the wireless communication apparatus employs OFDM (orthogonal frequency division multiplexing) as a modulation technique, the transmission-timing controlling unit causes timings of transmitting the frames from the transmitting units to match each other by adjusting a length of a cyclic prefix inserted in each of the frames and by changing the length of the cyclic prefix between the frames, the cyclic prefix being generated by copying a rear part of a OFDM symbol.
