Frequency Domain Reflectometry (FDR) is a technique that was proposed for fault detection in Digital Subscriber Line (DSL) cables. In this paper, the authors describe how FDR can be used to determine the topology of power line networks. To this end, they first infer distance information from the multiple signal reflections measured and processed with FDR. Then, they present an algorithm that uses these distance measurements to reconstruct the topology step by step operating on a network graph. Numerical results for sets of sample networks demonstrate the effectiveness of the proposed topology-inference approach.
