摘要： A radio transmitting apparatus wherein unnecessary consumption of transmission power can be suppressed and PAPR (Peak to Average Power Ratio) can be reduced in multicarrier communication. In the apparatus, a repetition part (105) replicates (repeats) each symbol outputted from a modulating part (103) to generate and output a plurality of identical symbols to an S/P part (107), which converts the symbol sequence outputted in series from the repetition part (105) into parallel symbol sequences and outputs them to an interleaver (109). The interleaver (109) then reorders the symbol sequences outputted from the S/P part (107) and outputs them to a mapping part (111), which removes, in accordance with the propagation path quality of each of subcarriers constituting OFDM symbols that are multicarrier signals, some of the identical symbols as replicated by the repetition part (105) and then maps the rest of the symbols onto subcarriers for application to an IFFT part (113).
