摘要： In a wireless transmission method and wireless transmitter using a plurality of antennas at least in signal transmission, a process requiring a high immediateness is enabled to implement at the reception end. A wireless communication apparatus, for making a transmission based on a transmission unit being specified as a predetermined plurality of symbols, sends a plurality of symbols other than the last N symbols (N is an integer equal to or greater than 1) of the transmission unit through use of a plurality of antenna, and the last N symbols of the transmission unit through use of one antenna.
