  • RADIO TRANSMITTING APPARATUS AND RADIO TRANSMITTING METHOD
    Publication number: 20090161789
    Abstract: Disclosed are a radio sending device and a radio sending method for improving a throughput while keeping a receiving quality. In this radio sending device, an MCS switching control unit (102) applies an MCS parameter having a lower quality required than that of the MCS parameter to be applied to send data arranged at other than the two end portions of a block, to send data arranged at the two end portions of the block, and a CP adding unit (105) adds such a CP to the leading end of the block as is created by copying the trailing end portion of the block composed of the send data, to which the MCS parameter is applied by the MCS switching control unit (102), with a length less than the delay time of the maximum delay wave. A send RF unit (106) sends the send data, in which the CP is added to the leading end of the block, from an antenna (107).
