<P>PROBLEM TO BE SOLVED: To provide a BICM-ID (Bit Interleaved Coded Modulation-Interactive Decoding) method having a small transmission rate loss and a little processing amount of a decoder. <P>SOLUTION: A wireless communication device conducts a coding 10 by the code based on a repeated code, and providing multiplexing modulation 12 by an extended mapping to transmit through the interleave process 11 for exchanging the order of each coded bit. The extended mapping includes the reduction process of the number of bits from l bit to m bit (m<l) and non-Gray mapping, and the reduction process of the number of bits is determined so that at least one bit of the predetermined number of bits is determined by only one of the interleaved bits. <P>COPYRIGHT: (C)2010,JPO&INPIT |
