Characterization of Indoor Ultra-wide Band NLOS channel

Characterization of indoor UWB non-line-of-sight (NLOS) channel is done by using new algorithm manipulate of Win's experimental data. A statistical model is then proposed based on these new characteristics. The model has the flexibility to deal with the "soft NLOS" and the "hard NLOS" environment, which is shown in measurements, by defining the polarity of a particular model parameter. Therefore, the channel impulse responses (CIR) generated by the proposed mode "resemble" the measured channel impulse responses better than SV/IEEE 802.15.3a model in terms of the cumulative distribution functions (CDFs) of the small-scale statistics, instead of just the average values
