    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: An embodiment method includes: performing balancing processing on a data stream that includes a plurality of sub-data stream segments, and performing segment de-interleaving on a data stream obtained after the balancing processing. The method further includes separately performing forward error correction (FEC) decoding on each sub-data stream segment in a data stream obtained after the segment de-interleaving. The method further includes performing, according to a balancing termination state of each sub-data stream segment obtained after previous balancing processing, balancing processing on each sub-data stream segment obtained after the FEC decoding, and performing FEC decoding on the data stream obtained after balancing processing is performed on each sub-data stream segment. When it is determined that a preset iteration termination condition is met, the method includes outputting the data stream obtained after the FEC decoding.

    Abstract: This application discloses a modulation/demodulation and encoding/decoding method and belongs to the field of communication technologies. The modulation and encoding method includes: grading to-be-transmitted bits into a plurality of levels; encoding a plurality of levels of bits obtained through grading to obtain a plurality of levels of codewords; and mapping the plurality of levels of codewords to a symbol in a staggered manner, where the plurality of levels of codewords include a first codeword, the first codeword is located at a Yth level of the plurality of levels of codewords, and the first codeword overlaps at least one codeword at any level other than the Yth level. In this way, codewords at different levels are associated by using a symbol to which the codewords are mapped, and an overlapping part between a plurality of codewords can assist in demodulating the codewords.
