Abstract
Techniques for estimating distances to irregularities on a subscriber loop are described. A loop response is measured in the frequency domain. The loop response is weighted by a prolate spheroidal wave function to yield a weighted response. The weighted response is transformed to a spectral domain, and peaks in the spectral domain are identified as the distances to the irregularities.
