We propose a technique of crosstalk reduction through power lines. This crosstalk reduction technique uses the pseudo-matched impedances’ method that determines the characteristic parameters of the chosen line through the transmission lines’ theory. Besides, we establish the telegrapher's equations to determine the characteristic impedances of the line. Further, two types of lines are employed here to apply the pseudo-matched impedances’ method. The far-and near-ends crosstalk are measured with two strategies known as Simulink diagram and Matlab code. The Simulink diagram of the power line provides crosstalk curves and the Matlab code directly returns crosstalk values. It appears that the crosstalk has a reduction rate between 20 and 50% compared to previous investigations using pseudo-matched impedances in literature. Moreover, the variation of two different types of impedances leads to a crosstalk reduction rate that approaches 99%.
