PROBLEM TO BE SOLVED: To provide a multi-carrier transmitter capable of allocating accurate subcarrier transmission power.SOLUTION: A multi-carrier transmitter, for transmission with controlling transmission power among subcarriers in multi-carrier transmission, includes: a digital processing part including serial to parallel conversion means for parallelizing process to allocate a symbol string inputted in series to a predetermined number of subcarriers, and inverse Fourier transform processing means for performing inverse Fourier transform process for a symbol string of subcarriers, which is a group of subcarriers in power value allocation basis; and an analog processing part including analog signal processing means for generating a transmission signal by converting an output signal from the inverse Fourier transformation means to an analog signal, the number of the analog signal processing means being the same as the number of the power values allocated. The multi-carrier transmitter generates and transmits a transmission signal with allocating transmission power different for each subcarrier, by allocating different power to each of signals outputted by the analog signal processing means. |
