By switching between an SFBC and a CDD according to required transmission power in an uplink, the transmission diversity of the uplink is efficiently performed. A wireless transmitter which includes transmitting antennas 21-1, 21-2 and selects any of plural kinds of transmission diversity scheme to perform the transmission diversity includes a transmission power deciding section 14 that decides transmission power based on information notified from a receiver which is a transmission destination, a transmission diversity scheme selecting section 15 that selects any one of the plural kinds of transmission diversity schemes based on the decided transmission power, and a switching section 16, an SFBC coding section 17, a CDD section 18, IFFT sections 19-1, 19-2, CP inserting sections 20-1, 20-2, and the transmitting antennas 21-1, 21-2, which perform wireless transmission to the receiver using the selected transmission diversity scheme.
