Arrangement for estimating power cross-coupling from signal lines to investigation line computes coupling coefficient per signal line using frequency point power values for investigation, signal lines

摘要

A device (31) receives power values at a number of frequency points greater than the number of signal lines in a frequency band for the signal lines and the investigation line, and a device (32) computes a coupling coefficient per signal line representing coupling of power for the corresponding signal line to the investigation line using the power values at the frequency points for the investigation and signal lines. Independent claims are also included for the following: (a) a method of estimating power cross-coupling from a number of signal lines to an investigation line (b) a noise signal generator for supplying noise signal power on an investigation line (c) a method of supplying noise signal power on an investigation line (d) a device for dimensioning a transmission system with a number of transmission lines (e) a method of dimensioning a transmission system with a number of transmission lines (f) a computer program .
