Abstract
A transmission apparatus comprising: a spreading section configured to spread transmission data by discrete Fourier transform to generate a first multi-carrier signal; a data selection section configured to select, based on control information, one of the first multi-carrier signal and a second multi-carrier signal that is not spread by the spreading section; and an RF section configured to transmit one of the first and second multi-carrier signals simultaneously from each of a plurality of frequency channels. An OFDM transmission apparatus comprising: a variable-spreading-factor spreading section configured to perform discrete Fourier transform on data signals to generate at least one spread signal; a sub-carrier allocation section configured to allocate the at least one spread signal to a plurality of sub-carriers; an inverse discrete Fourier transform section configured to perform inverse discrete Fourier transform on the at least one spread signal allocated; and a control section configured to control, according to the number of the at least one spread signal, a limit of a power for transmitting the data signals.
