The study on Crosstalk of Single Wire and Twisted-Wire Pair

A method based on time-domain Baum-Liu-Tesche (BLT) equations of transmission line model is presented in this paper for solving the crosstalk problem between a single wire and a twisted-wire pair. The single wire and the twisted-wire pair (TWP) together are modeled as a set of uniform multi-conductor transmission lines with abrupt interchanges of wire positions at the end of each loop of the twisted-wire pair, each group of multi-conductor transmission lines is solved by using the finite-difference time-domain (FDTD) method, the nodes of the twisted pair are corrected by using twisted-wire pair two-line hybrid iterative method. Finally, the time-domain results are obtained. It is found that the simulation results obtained by using BLT equations proposed in this paper agree very well with the results of commercial simulation software, the method is verified to be corrected.
