摘要： A method, a device, and an apparatus for correcting bursts are disclosed. The method includes: calculating a correction vector according to a received codeword and a check matrix, wherein the check matrix is an Overlapped Quasi Dual Diagonal Matrix; determining a length and position of a burst according to a longest zero element vector between two nonzero elements in the correction vector when the correction vector is nonzero; and calculating out an error mode according to the correction vector and the length of the burst, obtaining an error mode polynomial according to the error mode, correcting the received codeword according to the error mode polynomial, and obtaining a corrected codeword polynomial. The PBC-based implementation method for cyclic codes herein can correct more burst errors than the conventional cyclic code decoding method.

摘要： The embodiments of the present invention provide a data coding method. In this data coding method, a synchronization header is added to the data that has undergone line coding and FEC coding, and then the data is framed and sent out. The embodiments of the present invention also provide the corresponding data decoding method, data coding apparatus, and data decoding apparatus. Because the redundant information for synchronization is added, the synchronization performance of the transmission system is ensured effectively even if the algorithm selected in the line coding provides low redundancy; moreover, the added synchronization header does not participate in the FEC coding calculation, thus preventing impact on the FEC coding gain.
