Crosstalk is the major limiting issue in VDSL2 system.A class of low complexity and effective iterative crosstalk cancellation algorithms based on matrix splitting and iterative theory are proposed for VDSL2 upstream transmission.Two special iterative algorithms based on diagonal matrix splitting and up triangular matrix splitting are discussed
as the two splitting inspired from using the channel matrix property of diagonal dominant and column wise diagonal dominant respectively.These results reveal that the iterative method based on up triangular matrix splitting is superior to other iterative algorithms
and its performance approaches zero forcing algorithm
but the complexity in each iteration step is almost the same as first order algorithm.Computer simulation results based on measured data verify the efficiency of the new proposed method.
