Abstract
A signal processing method, device, and system are provided. The method includes: sending, through a first user port, a crosstalk detection signal in a connected line, and receiving, through a second user port, an error sample of an actual downlink signal fed back by a terminal side in a connected line; and estimating, according to the actual downlink signal and the crosstalk detection signal, a coefficient of a pre-coder of a DSLAM to obtain an estimated coefficient of the pre-coder, where the coefficient of the pre-coder is used to cancel far-end crosstalk on the line connected to the second user port when the first user port sends an SELT signal.
