1. A communication device, comprising:
a first CRC addition unit that adds a first CRC sequence to an information sequence to be transmitted;
a division unit that divides an information sequence having the first CRC sequence added thereto into a plurality of sequences;
a first FEC coding unit that implements first FEC coding by using a sequence obtained by division;
a second CRC addition unit that adds a second CRC sequence to a coded sequence obtained after the first FEC coding;
a second FEC coding unit that implements second FEC coding by using a coded sequence having the second CRC sequence added thereto;
a coupling unit that couples coded sequences obtained after the second FEC coding;
a transmitting unit that transmits a coded information sequence obtained after coupling to another communication device; and
a retransmission control unit that controls retransmission with the coded sequence obtained after the first FEC coding as a unit.
