The method includes: determining that there is no to-be-sent downstream signal on m subscriber lines in n subscriber lines; superimposing a signal X on the m subscriber lines, so that a signal output on the m subscriber lines after precoding processing is 0, where xm indicates a signal component loaded on the mth subscriber line in the m subscriber lines; performing precoding processing on a downstream signal on the n subscriber lines; and sending the downstream signal that has undergone the precoding processing on another line except the m subscriber lines in the n subscriber lines. The embodiments of the present invention further provide a network-side device and a DSL system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal processing method in DSL system, apparatus, and system","description":"Embodiments of the present invention provide a signal processing method in a DSL system.
