Disclosed in the embodiments of the present invention are a digital subscriber line signal processing method, a device and a digital subscriber system. The signal processing method comprising: use symbols of frames to be transmitted to carry data to be transmitted; obtain the number of remaining symbols, said remaining symbols not carrying any data to be transmitted and being located within the frame to be transmitted carrying data to be transmitted; within the frame to be transmitted carrying data to be transmitted, add quantitative information of the remaining symbols and send frames carrying data to be transmitted and having quantitative information of remaining symbols. The embodiments of the present invention, by means of adding quantitative information of remaining symbols not carrying data to be transmitted, informs the receiver of the existence of remaining symbols not carrying data to be transmitted. Thus, processing is not executed on remaining symbols, thereby saving processing power for the TDD DSL system, reducing consumption, and causing the TDD DSL system to be energy efficient. |
