ENCODING APPARATUS, ENCODING METHOD AND RECODING MEDIUM WITH ENCODING PROGRAM RECORDED THEREON, AND DECODING APPARATUS, DECODING METHOD AND RECORDING MEDIUM WITH DECODING PROGRAM RECODED THEREON |
摘要 |
PROBLEM TO BE SOLVED: To perform correction encoding and decoding by a concatenated coding modulation mode of small circuit scale and high-performance. SOLUTION: In a encoding apparatus 1, a interleaver 20 permutes each bit for data composed of 3 bit series supplied from a convolution encoder 10 so that it will be encoded without fail, a convolution encoder 30 minimizes a total value of a Hamming distance of input bits between paths that is a Euclid distance and a multiple value modulation mapping circuit 40, when the smaller the distance between signals on Q plane, causes the Hamming distance in the convolution encoder 30 to correspond to the smaller one to map data of 3 bits supplied from the convolution encoder 30.
