A transmitting apparatus that converts a transmission digital signal to a high-frequency analog signal and transmits the high-frequency analog signal using a plurality of transmission frequencies, the transmitting apparatus including: a dividing unit that divides a transmission signal sequence into a plurality of blocks; a sub-block generating unit that applies pre-coding processing to the blocks and further divides the blocks after the pre-coding processing into sub-blocks; a frequency allocating unit that generates a frequency signal in which the sub-blocks are allocated to the transmission frequencies; and an inverse DFT processing unit that transforms the frequency signal into a time signal, wherein the transmitting apparatus sets the time signal as the transmission digital signal.
