MULTI-CARRIER COMMUNICATION DEVICE AND MULTI-CARRIER COMMUNICATION METHOD

摘要

A sequence converting section 104 interchanges 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 section 105 for each retransmission. The M-ary modulating section 105 performs 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 section 109.
