Method for efficient calculation of power sum cross-talk loss |
摘要 |
An efficient method for calculating Power Sum cross-talk loss is provided. Cross-talk loss measurements may include near-end cross-talk (NEXT) loss, far-end cross-talk (FEXT) loss, multiple disturber NEXT (MD NEXT) loss, and multiple disturber FEXT (MD FEXT) loss. Pair-to-Pair cross-talk loss responses are collected between a given wire pair and all the other wire pairs of concern, with each pair-to-pair cross-talk loss measurement having a number of frequency data points corresponding to the frequencies of interest. The pair-to-pair cross-talk loss response having the lowest positive value for a particular frequency data point is first selected as the baseline cross-talk loss response. The effects of each of the remaining pair-to-pair cross-talk loss responses on the baseline cross-talk loss response are then accounted for by applying power sum contribution values obtained from a look-up table. In this way, Estimated Power Sum cross-talk loss may be calculated for each of the corresponding frequency data points from each of the pair-to-pair cross-talk loss measurements in an efficient manner.
