Abstract
A data transmitting apparatus performs symbol mapping on each of first and second input data to generate a plurality of first and second modulation data symbols, performs inverse fast Fourier transform (IFFT) on the plurality of first and second modulation data symbols to convert the same into first and second real signals of a time domain from a frequency domain, angle-modulates the first and second real signals, and transmits the same to a data receiving apparatus. Thus, a peak-to-average power ratio (PAPR) can be lowered, while the same data transfer amount as that of the general OFDM data transmitting apparatus is maintained.
