摘要： Error correction coding and decoding according to a serial concatenated modulation system are carried out under high code rate. A coding apparatus 1 comprises three convolutional coders 10, 30 and 50 for carrying out convolutional operation; two interleavers 20 and 40 for rearranging order of data input; and a multi-value mapping circuit 60 for carrying out mapping of a single point on the basis of a predetermined modulation system. The coding apparatus 1 carries out convolutional operation whose code rate is “⅔” as coding of extrinsic codes by a convolutional coder 10, and carries out convolutional operation whose code rate is “1” as coding of inner codes by a convolutional coder 50, and a multi-value modulation mapping circuit 60 applies mapping to a transmission symbol of a 8 PSK modulation system to output it as a single code transmission symbol.

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： A decoder that receives, as input, probability information AMP/CR×yt. This probability information is obtained by dividing a channel value obtained by multiplication of received value yt and a predetermined coefficient AMP by the first additive coefficient CR for regulating the amplitude of the received value yt and the probability information 1/CA×APPt obtained by multiplying the a priori probability information APPt by the reciprocal of the second additive coefficient CA for regulating the amplitude of the a priori probability information APPt to a soft-output decoding circuit. The soft-output decoding circuit, which may be a large scale intergrated circuit, generates log soft-output CI×Iλt and/or external information 1/CA×EXt using additive coefficients for regulating the amplitude of arithmetic operations in the inside of the soft-output decoding circuit.

摘要： An encoding device in a data transmission/reception system includes a first convolutional encoder that encodes an outer code, an interleaver that permutes input data, a second convolutional encoder that encodes an inner code, and a muti-level modulation mapping circuit that performs signal-point mapping based on eight-phase shift keying. When the encoding device uses the second convolutional encoder having two or more memories, the first convolutional encoder uses, as the outer code, a code with a minimum output distance greater than the maximum input distance at which the minimum-distance inner code is generated.
