Disclosed are a signal processing method, apparatus and system, wherein the signal processing method comprises: a disturbed device receives, on an in-band frequency band thereof, a signal to be processed from a central-office-side device; the disturbed device receives, on out-of-band frequency bands of various disturbing devices, various near-end crosstalk signals from the various disturbing devices, both the disturbed device and the various disturbing devices belonging to a user-side device corresponding to the central-office-side device; the disturbed device calculates, according to the various near-end crosstalk signals, various near-end crosstalks received on the in-band frequency band of the disturbed device itself from the various disturbing devices; and the disturbed device performs, according to the various calculated near-end crosstalks, near-end crosstalk elimination processing on the signal to be processed. The signal processing method, apparatus and system of the present embodiment can offset a near-end crosstalk at a CPE side and improve the rate of a DSL system. |
