ABSTRACT:
A sequence converting section104interchanges high-order bits where an error does not easily occur and low-order bits where an error easily occurs that are used by an M-ary modulating section105for each retransmission. The M-ary modulating section105performs M-ary modulation using the high-order bits and low-order bits interchanged for each retransmission. An M-ary modulated symbol is interleaved with an interleave pattern being different for each retransmission, and multicarrier transmitted via an OFDM transmitting section109.
