Abstract

Crosstalk is the major limiting issue in VDSL2 system. Based on matrix splitting and iterative theory, a general form of iterative crosstalk cancellation algorithm is first proposed for VDSL2 upstream transmission. From using diagonal dominant and column wise diagonal dominant of crosstalk channel matrix property, two special iterative algorithms are then derived. Computer simulation results based on measured data verify that the iterative crosstalk cancellation algorithms can improve the performance and approach zero-forcing algorithm by successive iterations.
