    Abstract: This application discloses example decoding methods, example decoders, and example decoding apparatuses. One example decoding method includes performing soft decision decoding on a first sub-codeword in a plurality of sub-codewords to obtain a hard decision result. It is determined whether to skip a decoding iteration. In response to determining not to skip the decoding iteration, a first turn-off identifier corresponding to the first sub-codeword is set to a first value based on the hard decision result. The first turn-off identifier indicates whether to perform soft decision decoding on the first sub-codeword in a next decoding iteration. The soft decision decoding is not performed on the first sub-codeword in the next decoding iteration when a value indicated by the first turn-off identifier is the first value. The hard decision result is stored.

    Abstract: Embodiments provide a data encoding method, a data decoding method, and a related device. The method includes a transmitting end device that determines N data symbols at a same symbol location of N links of service data, where N is an integer greater than 1, and quantities of bits in all data symbols are the same. The transmitting end device performs forward error correction (FEC) encoding on the N data symbols to obtain a codeword, where the codeword includes the N data symbols and M overhead symbols, M is an integer greater than or equal to 1 and less than or equal to N, and a quantity of bits in each data symbol is the same as a quantity of bits in each overhead symbol. The transmitting end device sends the N data symbols through N service channels, and sends the M overhead symbols through M overhead channels.

    Abstract: This application provides a signal transmission method and system, and relates to the field of communications technologies. The system includes an equalization module, a first decoder, and a feedback module. The equalization module includes at least two multi-symbol detectors. The feedback module is connected to the first decoder and the at least two multi-symbol detectors. The equalization module performs equalization processing on convolutional data flows to obtain an equalized data flow. In this process, each multi-symbol detector performs multi-symbol detection processing on a convolutional data flow input into the multi-symbol detector. The first decoder decodes the equalized data flow to obtain a decoded data flow. The feedback module feeds back a feedback data flow to the at least two multi-symbol detectors. The equalization module performs equalization processing on the convolutional data flows based on the feedback data flow.
