Crosstalk-reduction based on phase synchronization between crosstalk and interference source signal

A method that can reduce crosstalk by using the inverted signal at the middle of aggressor line is presented in this paper.It is based on the synchronization feature of phase changing between crosstalk and interference source signal.In a bus system with n lines,phase inversions are set at the middle of the odd(or even)number line,then the amplitudes of far-end crosstalk,which come from the front and the back half coupling length, are numerically equal and the phases are opposite.The far-end crosstalk on transmission line would be set-off when these two parts of crosstalk signals are added automatically. Simulation results show that crosstalk can be eliminated mostly by this method.
