摘要
efficient as a DSL transmitter and receiver to estimate the crosstalk interference is disclosed. When transmission on the DSL cable, the line of each of the cable results in the form of crosstalk interference on the signals traveling through the other line. To reduce the complexity of the crosstalk estimation time key calculation, the transmitter signal is smaller than all of the plurality of sub-slots QAM +1 or -1 with the modulated-transmits the measurement signal having a matrix containing matrix. On the other hand, the residual signal is modified with the slots QAM 0, which does not require any processing for the crosstalk estimation. Instead of calculating the crosstalk vector of all the lines, the receiver only sub-it is necessary to calculate the crosstalk vector only for the signal slot in the nested matrices, the complexity is significantly reduced thereby ;
