    摘要: A method and apparatus for transmitting information data using a repetition coding scheme in a wireless communication system are disclosed. The transmission method includes generating a codeword of a predetermined size Nencoded by encoding information data of a size Ninfo, and transmitting the codeword to a receiver. The codeword includes a plurality of repeated blocks based on the information data and if the information data includes an odd number of 1s, the information data of odd-numbered repeated blocks out of the plurality of repeated blocks are bit-inverted.

    摘要: A data error correction system is provided which is capable of executing repeated error correction processing, and which improves the quality of communication lines by allowing repeated corrections of errors generated in the transmission line. The data error correction system comprises a Viterbi decoder 13 for decoding a designated encoded data from a buffer 12 and a block decoder for executing decoding of the data corresponding to a length of a block code after being decoded from the Viterbi decoder 13, when error correction is possible. When error correction is not possible, the data error correction system controls execution of re-decoding by the Viterbi decoder for executing error correction of the data corresponding to a length of a block code whose correction has not been possible yet at this stage.

    摘要: This application discloses a coding method and a communications device. The coding method includes: determining, by a communications device, a second transport block, where the second transport block includes a first transport block and check information corresponding to the first transport block; determining, by the communications device according to scheduling information of the second transport block, a scheme for performing outer-code coding on the second transport block; determining, by the communications device, a third transport block, where when the scheduling information meets a preset condition, the third transport block is a transport block obtained by performing outer-code coding on the second transport block, or when the scheduling information does not meet a preset condition, the third transport block is specifically the second transport block; and performing, by the communications device, inner-code coding on the third transport block according to a predefined rule. According to the foregoing solution, a transmission resource can be effectively used, transmission resource utilization can be improved, an error floor of inner-code coding can be lowered, and data transmission reliability can be increased.
