The Propagation Characteristics of Ultra-Wide Band Signals in Indoor Line-of-Sight Wireless Channel

摘要

By exploring the deterministic characteristics of the measurement data, a new propagation model with two deterministic clusters and stochastic arriving rays within each cluster is proposed. When considering cumulative distribution function (CDF) of the three key channel statistics, the proposed model fits the measurement data better than SV/IEEE 802.15.3a model which is seen as standard model for UWB indoor propagation channel. That means, with the additional knowledge of the specific environment geometry, the proposed model generating impulse responses "resemble" the measured channel impulse responses better than IEEE model. Moreover, the proposed model''s parameters obtaining procedure is simplified by utilizing simple parameters of physical channel.
