摘要：The present invention provides a crosstalk estimation method, an apparatus,and a system. According to the crosstalk processing method, the apparatus, and the system provided in embodiments of the present invention, a transceiver of a line
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, so that a receiver of the line can determine sample errors respectively according to the different pilot training signals. Then, the vectoring control entity determines crosstalk channel coefficients from the another 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, so as to eliminate impact of crosstalk from the another line to the inband and out-of-band spectrums of the line. This reduces impact on a line rate caused by inter-line crosstalk in a system in which lines of different profiles coexist, and further improves effects and stability of FTTC acceleration.
