Abstract	In this paper, we introduce a new method for distributed wire diagnosis by reflectometry. Distributed diagnosis consists in making reflectometry measurements at several points of a complex network at the same time, thus allowing to solve ambiguities due to the existence of multiple paths. Thanks to this, the exact position of any electrical fault or other specific singularity can be found in a complex network. Since several reflectometry modules are injecting test signals simultaneously, specific signal processing methods are needed to remove interferences between concurrent modules, namely, the interference noise. The method presented in this paper provides several advantages upon known state-of-art and is particularly well suited when used on running target systems, namely, the on line wire diagnosis.
