File name:. A stochastic non-line-of-sight (NLOS) ultraviolet (UV) communication channel model is developed using a Monte Carlo simulation method based on photon tracing. The expected channel impulse response is obtained by computing photon arrival probabilities and associated propagation delay at the receiver.
This method captures the multiple scattering effects of UV signal propagation in the atmosphere, and.

Recent advances in the design and manufacturing of ultraviolet (UV) devices, such as UV light-emitting diodes (LEDs), have produced much interest in the use of UV light for a wide range of application, including communications .The unique characteristics of the atmospheric propagation of deep-UV radiation (– nm) presents the novel opportunity of forming non-line-of-sight (NLOS Cited by: And, atmospheric scattering is very strong, enabling non-line-of-sight (NLOS) communications where the transmitter is not necessarily within the receiver field of view (FOV).
However, in addition to scattering, strong atmospheric absorption leads to significant signal attenuation and so limits achievable by: In this study, the long-distance non-line-of-sight (NLOS) ultraviolet (UV) communication channel is characterised using experimental data and theoretical modelling.
Experimental measurements of path loss and pulse broadening effects at distances of up to 4 km are reported and analysed, and comparisons between the field test data and a Monte Carlo multiple-scattering channel model provides Cited by: Space-Based Laser Communications Break Threshold.

A Monte Carlo computer simulation was developed to model hypothesized electro-optic laser communication systems operating in the middle ultraviolet. 1. Introduction. Non-line-of-sight (NLOS) scattering communication is based on the optical scattering theory.
Compared with the traditional communication, it has a lot of advantages, such as the good secrecy, good anti-jamming ability as well as the ability of bypassing theLerner and Kennedy analyzed the characteristics of atmospheric optical scattering channel, which.

Non-Line-of-Sight Electro-Optic Laser Communications in the Middle Ultraviolet. An experimental test-bed using a narrow-pulsed ultraviolet (UV) laser and high-bandwidth photomultiplier tube was set up to characterize pulse broadening effects in short-range non-line-of-sight (NLOS) scattering communication channels.
The solar-blind ultraviolet (UV) spectrum has useful properties for wireless communication and sensing. Strong atmospheric scattering in the UV spectrum enables non-line-of-sight (NLOS) communication.
The authors present recent experimental and analytical results in NLOS UV channel modelling, including impulse response and path loss. The authors further study the NLOS Cited by:.
