Multi-carrier communication method and multi-carrier communication apparatus

Abstract

SFTD coding section 10 adjusts a sequence of frequency arrangement and phases of transmit data digital symbols in a time series and thus generates at least two transmit signals. The transmit signals are transformed into parallel signals in serial/parallel transform sections 11 and 12, and subsequently transformed into OFDM signals in IDFT sections 13 and 14 and parallel/serial transform sections 15 and 16, respectively. In this way, by using the multicarrier transmission scheme, it is made possible to encode on the frequency axis signals conventionally encoded only on the time axis, and it is thus possible to decrease the processing delay while obtaining the same diversity effect as in the STTD transmit diversity scheme.
