SYSTEMS AND METHODS FOR LOOP LENGTH AND BRIDGED TAP LENGTH DETERMINATION OF TRANSMISSION LINE

Title:

SYSTEMS AND METHODS FOR LOOP LENGTH AND BRIDGED TAP LENGTH DETERMINATION OF TRANSMISSION LINE

Document Type and Number:

Japanese Patent JP2010148120

Kind Code:

A

Abstract:

To provide a method for estimating a loop length, the number of bridged taps and a length of bridged taps on a transmission line.

Through the use of a least squares minimization concept, a loop length, the number of bridged taps and a length of the bridged taps on a transmission line can be determined from readily available modem data. In particular, the loop length, the number of bridged taps and the length of bridged taps can be estimated by comparing a measured frequency domain channel impulse response of the transmission line to a model of a loop that is comprised of multiple sections and multiple bridged taps.
