Abstract
According to one embodiment, a transmission device includes an insertion unit, an allocation unit, a division unit, an IFFT unit, a phase rotation unit, and a transmission unit. The phase rotation unit performs a phase rotation to reduce a PAPR characteristic for each block on which inverse fast Fourier transform has been performed. The transmission unit combines transmission signals, on each of which a phase rotation has been performed by the phase rotation unit, and transmits the combined transmission signal to an external device. In addition, the division unit includes a predetermined band and at least one pilot symbol located outside another of end of this predetermined band on an opposite side of the one end into one block.
