UWB Channel Modeling Improvement in Indoor Line-of-Sight (LOS) Environments

Channel measurement and modeling are important issues when designing ultra wideband (UWB) communication systems. A Precise model of the channel response is inevitable for designing a UWB telecommunication system. In this article signal propagation in indoor environment and LOS condition is evaluated and the appropriate model of this scenario is presented. Parameters such as the power delay prof...

Clusterization Analysis of Spatio-Temporal UWB Radio Channel for Line-of-Sight and Non-Line-of-Sight Indoor Home Environment

In this paper, spatio-temporal analysis of LOS and NLOS home environments based on the deterministic approach are presented. The detected paths were classified into several clusters by a heuristic approach. The identified clusters were determined from the physical structures of the environment, i.e. room height, specular directions and size of scatterers in both LOS and NLOS case, which means t...

A Novel Approach based on UWB Beamforming for Indoor Positioning in None-Line-of-Sight Environments

Accurate wireless indoor positioning in non line-of-sight (NLoS) environments is an open research topic due to interfering dense multipath propagation. The key challenge is to reliably detect the direct path (DP) from the transmitter to the receiver so as to enable accurate positioning calculations. In our contribution a novel approach called ”BeamLoc” has been introduced to perform this task. ...

Line of Sight (LOS) rate estimation in strap down seekers using discrete-time extended state observer.

The line of sight (LOS) rate is a parameter that is needed to calculate the acceleration applied to missiles by the proportional guidance laws in order to hit the target. This rate is usually measured using gimbaled seekers. However, if the type of missile seeker be strap down, the LOS rate must be calculated from deriving the missile's seeker output angles or estimation methodes. The derivatio...

Narrowband MIMO Channel Modeling for LOS Indoor Scenarios

Herein, a line-of-sight (LOS) multiple input multiple output (MIMO) channel model is presented based on 5.2 GHz indoor MIMO channel measurements. The signal from the dominant direction is estimated and removed from the channel data. The residual part is shown to be Rayleigh distributed and its covariance matrix can be well approximated by the Kronecker product of the covariance matrices seen fr...
