Patent ID: 8855235

Claim:
A transmission apparatus, comprising: a multiplier configured to multiply a first in-phase (I) channel signal and a first quadrature (Q) channel signal for a symbol provided on a complex plane by a multiplication coefficient and output a second I channel signal and a second Q channel signal, a transmission power of constellation points of the second I and Q channel signals being obtained in accordance with a comparison between a number of one or more transmission sub-carriers allocated for the symbol and a given number relating to a transmission sub-frame that includes the symbol in a transmission frame; and an inverse fast Fourier transformer configured to perform an inverse fast Fourier transform on the second I and Q channel signals, wherein the given number comprises at least one of: a maximum number among a plurality of numbers, each of the plurality of numbers being a number of one or more transmission sub-carriers that are allocated for each of a plurality of symbols included in the transmission sub-frame; a minimum number among a plurality of numbers, each of the plurality of numbers being a number of one or more transmission sub-carriers that are allocated for each of a plurality of symbols included in the transmission sub-frame; and an average value of a plurality of numbers, each of the plurality of numbers being a number of one or more transmission sub-carriers that are allocated for each of a plurality of symbols included in the transmission sub-frame.
