Channel modelling and performance of non-line-of sight ultraviolet scattering communications
Channel modelling and performance of non-line-of-sight ultraviolet scattering communications Report Title The solar blind ultraviolet (UV) spectrum shows unique properties for wireless communication and sensing. Sufficient scattering in UV spectrum can make a non-line-of-sight (NLOS) communication scenario feasible. We present recent experimental and analytical results in non-line-of-sight UV c...
متن کاملModel of line-of-sight ultraviolet propagation
The traditional line-of-sight ultraviolet model cannot serve better for link performance study for the reason that the scattering characteristic is often ignored in the modelling process. Therefore, a line-of-sight ultraviolet bipyramid model in combination with transceiver full beam angles and geometrical relationship of the transceiver field of view intersection is established. The theoretica...
متن کاملNon-Parametric Non-Line-of-Sight Identification
Recently, there has been much interest in accurate determination of mobile user locations in cellular environments. A general approach to this geolocation problem is to gather time-of-arrival measurements from a number of base stations (BSs) and to estimate user locations using the traditional least square approach. However, in non-line-of-sight (NLOS) situations, measurements are significantly...
متن کاملLine 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...
متن کاملExperimental performance evaluation of non-line-of-sight ultraviolet communication systems
Motivated by rapid advances in solar blind ultraviolet (UV) light emitting diodes (LEDs), filters and photomultiplier tubes (PMTs), together with unique UV atmospheric propagation characteristics, a non-line-of-sight (NLOS) UV communication test-bed has been recently built and utilized for extensive experimental evaluation of performance of NLOS UV links in outdoor environments. Towards this en...
