Abstract
A crosstalk processing method, an apparatus, and a system comprise a transceiver of a line that generates, respectively according to pilot sequences allocated by a vectoring control entity, pilot training signals that are within different spectral ranges and that satisfy a preset relationship with a pilot training signal of another line such that a receiver of the line can determine sample errors respectively according to the different pilot training signals. A vectoring control entity then determines crosstalk channel coefficients from the other line into an inband spectrum and an out-of-band spectrum of the line, and performs precoding processing on a to-be-sent data signal of the line to eliminate impact of crosstalk from the other line to the inband and out-of-band spectrums of the line.
