Abstract
Embodiments of the present invention provide a robust channel (RC)-supporting coding and modulation method and apparatus. The method comprises: forming, on an interface between a PMD layer and a PMS-TC layer, a data frame by using bit data carried in a DMT symbol; determining first-part bit data in the data frame as uncoded bit data on the interface between the PMD layer and the PMS-TC layer, where the first-part bit data includes RC bit data, and coding second-part bit data in the data frame to obtain coded bit data; and mapping, at the PMD layer, the uncoded bit data and the coded bit data onto multiple subcarriers corresponding to the data frame, and performing modulation to obtain modulated subcarriers, where the RC bit data is mapped onto at least one RC subcarrier.
