    摘要: Provided is a wireless communication apparatus by which reduction of a diversity gain can be suppressed at minimum in the case of employing a repetition technology in multicarrier communication. In the wireless communication apparatus (100), repetition sections (102-1 to 102-n) repeat each data symbol inputted from modulating sections (101-1 to 101-n) to create a plurality of identical data symbols. An allocating section (103) outputs each data symbol to a multiplexing section (105) by allocating the data symbol to a plurality of subcarriers constituting an OFDM symbol. At this time, the allocating section (103) allocates at least one of the repeated identical symbols to a subcarrier different from a subcarrier to which the symbol is allocated in an adjacent sector.
