Patent ID: 8300519

Claim:
A method for crosstalk evaluation of a channel, the channel being represented by a multiple-input-multiple-output (MIMO) system connecting a first network component with at least one second network component, the MIMO system including first coefficients associated with transmission lines and second coefficients associated with crosstalk, wherein the crosstalk contains a far-end crosstalk portion and a near-end crosstalk portion, the method comprises the steps of: sending, via the first network component, a signal of a predetermined power density to one of second network components; and evaluating the far-end crosstalk portion and the near end crosstalk portion according to equation: H eff , k , l = H next , k , l + α l · H fext , k , l · H l with H fext , k , l = T long ⁡ ( H eff , k , l ) α l · H l wherein: H fext,k,l is a far-end crosstalk portion, H next,k,l is a near-end crosstalk portion H eff,k,l is a transfer function between a transmitting port k and a receiving port l, H l is a transfer function of a loop l, α l is a complex reflection coefficient, and T long is a linear operation utilizing a fact that the near-end crosstalk portion has a reduced runtime due to its limited propagation.
