Abstract
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.
