A Statistical Model for UWB Non-line-of-sight Indoor Environment
نویسندگان
چکیده
A new double-cluster statistical model for non-line-of-sight (NLOS) environment is proposed which is based on analysis of the experimental data. The model itself and the parameters estimating of the corresponding model are simplified. By defining the polarity of a particular model parameter, the model has the flexibility to deal with the “soft NLOS" and the “hard NLOS" environment. 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.

UWB Indoor Delay Profile Model For Residential and Commercial Environments
We present a statistical model for the delay profile of ultra-wideband channels in indoor environments. Two kinds of profiles are defined, namely the multipath intensity profile (MIP) and the power delay profile (PDP). The MIP is he delay profile at a point in space, while the PDP is a local spatial average. The model is based on 60,000 complex frequency response measurements from 20 commercial...
متن کاملA Hybrid TDOA/AOA Positioning Technique for Indoor UWB Systems
A hybrid TDOA/AOA positioning technique for indoor ultra wideband (UWB) systems is presented in this paper. The UWB system is a potential candidate for improving the location accuracy of indoor positioning due to the fine-resolution characteristic of the UWB signals. The hybrid technique consists of extended Kalman filters (EKF’s), which process time difference of arrival (TDOA) and angle of ar...

This paper presents a tutorial overview of ultrawideband (UWB) propagation models. The channels models IEEE 802.15.3a y IEEE 802.15.4a are revised and examined. Subsequently, the UWB channel in the frequency domain is analyzed. Results of the amplitude statistics in this domain and of the correlation coefficient between subcarriers in a MB-OFDM UWB system are obtained. In addition, the UWB chan...
متن کاملIndoor Non-directed Optical Wireless Communications - Optimization of the Lambertian Order
For an indoor non-directed line of sight optical wireless communication (NLOS-OWC) system we investigate the optimized Lambertian order (OLO) of light-emitting diodes (LEDs). We firstly derive an expression for the OLO from a conventional Lambertian LED model. Then, we analyze the indoor multi-cell NLOS-OWC channel characteristics including the optical power distribution and the multipath time ...
متن کاملNon-line-of-sight identification in ultra-wideband systems based on received signal statistics
Non-line-of-sight (NLOS) propagation can severely degrade the reliability of communication and localisation accuracy in indoor ultra-wideband (UWB) ‘location-aware’ networks. Link adaptation and NLOS bias mitigation techniques have respectively been proposed to alleviate these effects, but implicitly rely on the ability to accurately distinguish between LOS and NLOS propagation scenarios. A sta...
