Abstract
Provided is a transmission device which improves the error rate characteristic upon decoding when performing error correction encoding by using a self-orthogonal code or an LDPC-CC in a communication system using a communication path having a fading fluctuation, multi-value modulation, or MIMO transmission. In the transmission device, the self-orthogonal encoding unit (110) encodes a self-orthogonal code having a constriction length K and an interleave unit (130) rearranges a code word sequence so that the same modulation symbol includes an information bit of a moment i and a non-correlated bit of the information bit of the moment i in a multi-value modulation unit (150).
Claims15
A transmitting apparatus comprising:
- an encoding section that performs error correction encoding using a self-orthogonal code or LDPC-CC on an information symbol and generates a codeword symbol;
- an interleaver that rearranges an order of said codeword symbols;
- and
- a transmission symbol generation section that generates a transmission symbol using a plurality of said codeword symbols, wherein:
- said interleaver rearranges said codeword symbols so that correlation between a channel characteristic of said transmission symbol that includes said information symbol of point-in-time i and a channel characteristic of said transmission symbol that includes a non-correlated symbol of said information symbol of point-in-time i becomes high;
- and
- said non-correlated symbol is said codeword symbol that is not used in decoding of said information symbol of point-in-time i.
