摘要：
To carry out error correction coding and decoding according to a serially concatenated coded modulation system with a small circuit scale and high performance. A coding apparatus 1 is designed so that an interleaver 20 interleaves order of bits so that all weights are coded by a convolutional coder 30 with respect to data comprising a series of 3 bits supplied from a convolutional coder 10; the convolutional coder 30 makes as small as possible the total value of the hamming distance of input bit between passes to be the minimum Euclidean distance with respect to data of 3 bits supplied from the interleaver 20; and a multi-value modulation mapping circuit 40 causes the hamming distance of input bits in the convolutional coder 30 as the distance between signal point on the I/Q plane is smaller to subject data of 3 bits supplied from the convolutional coder 30 to mapping.
