A METHOD, DEVICE AND SYSTEM FOR ESTIMATING CHANNEL

摘要

A method for channel estimation includes: loading a combination of signals sent on other lines over a line of a channel; measuring a signal-to-noise ratio (SNR) of the loaded line; and calculating crosstalk channels of the loaded line according to a coefficient of the combination of signals sent on other lines and the measured SNR. Accordingly, a device and system for channel estimation are provided. The technical solution of the present invention may be used for relevant systems such as an x Digital Subscriber Line (xDSL) system.
