Abstract
Equipped with a plurality of mapping blocks 102 and 103 that carry out mappings of different rates, signals subjected to low-speed mapping are placed in the periphery of a band to which a plurality of sub-carriers are assigned at an interval corresponding to the symbol rate. The signal placed on the frequency axis in this way is converted to a time waveform through inverse Fourier transformation block 105, converted to a symbol time series through parallel/serial conversion block 106, then quadrature-modulated and transmitted.
