Abstract
Through the use of a least squares minimization concept, the loop length, the number of bridged taps and 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 bridge 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 bridge taps.

A loop length and bridged tap length estimation system comprising:
- a channel impulse response device that determines a channel impulse response for a transmission line;
- a modeling device that determines a theoretical channel impulse response;
- and
- a loop length and bridged tap determination device that determines a loop length and at least one bridged tap length based on a comparison of the channel impulse response and the theoretical channel impulse response.
A method for determining a loop length and at least one bridged tap for a transmission line comprising:
- estimating a channel impulse response;
- determining a theoretical channel impulse response;
- monitoring a difference between the theoretical channel impulse response and the estimated channel impulse response;
- and
- determining the loop length and at least one bridged tap based on an error minimization function.
An information storage media comprising information that determines a loop length and at least one bridged tap for a transmission line comprising:
- information that estimates a channel impulse response;
- information that determines a theoretical channel impulse response;
- information that monitors a difference between the theoretical channel impulse response and the estimated channel impulse response;
- and
- information that determines the loop length and at least one bridged tap based on an error minimization function.
