Ultra Wideband Channel Model for Indoor Environments

摘要

This paper presents an in-depth study of a ultra-wideband (UWB) indoor radio channel between 1 and 9 GHz, which was used for the subsequent development of a new statistical UWB multi-path channel model, focusing on short range indoor scenarios. The channel sounding process was carried out covering different indoor environments, such as laboratories, halls or corridors. A combination of new and traditional parameters has been used to accurately model the channel impulse response in order to perform a precise temporal estimation of the received pulse shape. This model is designed specifically for UWB digital systems, where the received pulse is correlated with an estimated replica of itself. The precision of the model has been verified through the comparison with measured data from equivalent scenarios and cases, and highly satisfactory results were obtained.
