Interference mitigation by decisions fusion in a non coherent UWB-IR receiver

摘要：

Multi-user interference is a major issue for non coherent ultra wide band impulse radio (UWB-IR) systems, since the commonly used energy integration prevents from distinguish useful and spurious impulses in the received signal. We propose a short integration based and multipath capable non coherent receiver, relying on a comparator. The decisions taken on the multipaths are combined and weighted by their reliability. Under interference situations, the coefficient of the interfered paths are updated to marginalize their impact in the combination process. Simulations show the relevance of such a proposition and also exhibit that a simple elimination of the interfered paths can provide satisfactory performance.
