Ultrawideband propagation channels - Theory, measurement, and modeling
(2005) In IEEE Transactions on Vehicular Technology 54(5). p.1528-1545- Abstract
- This paper presents an overview of ultrawideband (UWB) propagation channels. It first demonstrates how the frequency selectivity of propagation processes causes fundamental differences between UWB channels and "conventional" (narrowband) channels. The concept of pathloss has to be modified, and the well-known WSSUS model is not applicable anymore. The paper also describes deterministic and stochastic models for UWB channels, identifies the key parameters for the description of delay dispersion, attenuation, and directional characterization, and surveys the typical parameter values that have been measured. Measurement techniques and methods for extracting model parameters are also different in UWB channels; for example, the concepts of... (More)

Finally, channel models also have an important impact on the performance evaluation of various UWB systems. (Less)
