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.

摘要： In the invention, such replacement is performed that the sum of distances between two points before and after replacement is large, and in the case where replacement positions are regarded as a sequence, the sequence satisfies k-equidistributioness. At step S1, a replacement array by an affine interleaver is set. At steps S2 and S3, an M-sequence is generated, and a function L(t, u) is obtained by the existence position of 0 and 1. By data obtained through these processes, at step S4, a final replacement array is set.

摘要： A device for encoding turbo codes for use in satellite communications. Input data including termination bits are supplied to a series of interleaver circuits. Coding circuits perform convolution operations on data output from the respective interleavers, thereby obtaining coded data. The encoding process automatically results in terminated coded data. Thus, termination circuits are unnecessary. The determination of substitute positions by the respective interleavers through arithmetic computations makes it unnecessary to provide separate memory to store substitute position information.
