Abstract:
A method for determining reference virtual noise of Digital Subscriber Line (DSL), includes: obtaining a receiver-end-actual noise of DSL subcarriers; and determining a reference virtual noise according to the obtained receiver-end-actual noise of the DSL subcarriers. Furthermore, the invention also discloses a device for determining a reference virtual noise of DSL, and a method and a system for configuring the reference virtual noise of DSL. The invention can improve the accuracy of the reference virtual noise, thereby making the configuration of the reference virtual noise more accurate.
