Patent ID: 8170136

Claim:
A radio transmitting apparatus comprising: a control section that controls, out of transmission data assigned in a block as a processing unit of time-frequency conversion, error robustness of transmission data assigned to an end part of the block by applying (1) a modulation scheme having lower required quality than a modulation scheme applied to transmission data assigned to a part other than the end part of the block, (2) a coding rate having lower required quality than a coding rate applied to the transmission data assigned to the part other than the end part of the block, or (3) a combination of a modulation scheme and a coding rate having lower required quality than a combination of a modulation scheme and a coding rate applied to the transmission data assigned to the part other than the end part of the block, to the transmission data assigned to the end part of the block; and a transmission section that transmits the error robustness controlled transmission data in the block.
