The large bandwidth of Ultra-Wideband (UWB) signals induces a high temporal resolution of the multipath components of the propagation channel. Due to the variation of the propagation paths for different positions of the transmitter, a channel impulse response can act as a fingerprint for the position of the transmitter, if the position of the receiver is known. UWB Geo-Regioning is a localization or clustering method based on channel impulse response fingerprinting. In this paper, neural networks are used to perform Geo-Regioning. As input vector, either the complex values or the power values of the CIR are used. For performance evaluation measured channel impulse responses are used.
