“…The contribution of single-and multiple-scattering to the IRF is also examined for two cases. The first considers a typical case where single scattering dominates and the Gamma function of [26] can provide a good fit. Figure 5 depicts the IRF for the second case, that of a vertically pointed transmitter with beam width of 3 mrad and a vertically pointed receiver with a FOV of 10 • .…”

The unique characteristics of the atmospheric propagation of deep ultraviolet (UV) radiation make possible the novel capability of establishing non-line-of-sight (NLOS) optical communication links. Although NLOS UV communications (UVC) has been studied for decades, early work focused on the use of lasers and flash lamps as sources. Recent advances in device technology, including UV light-emitting diodes and solar-blind optical filters, suggest that compact low-power systems may soon be feasible, and, as a result, research into the effective use of this rapidly maturing technology has accelerated. In this paper, we review the NLOS UVC literature, examining a range of topics from channel modelling and experimentation through system analysis and prototype development. The breadth of this research not only indicates the growing interest in UVC technology but also suggests the existence of many avenues for continued exploration.

This thesis studies modeling of non-line-of-sight (NLOS) ultraviolet (UV) scattering channels and the corresponding communication link performance. The research focuses on the channel impulse response and path loss models based on extensive field measurements and theoretical characterization. In NLOS UV scattering environments, transmitted signals suffer from severe atmospheric attenuation and fading before arriving at a receiver, such as absorption, scattering, and turbulence. The thesis is devoted to development of analytical and experimental models to characterize NLOS UV communication channels. The author conducts comprehensive channel measurements for short communication ranges up to a few hundred meters and proposes an empirical path loss model. Meanwhile, an algorithm is developed to simulate the NLOS UV channel impulse response and path loss based on photons stochastic migration in the atmosphere. Effects of atmosphere conditions on single scattering and multiple scattering are investigated. An empirical curve-fitting model is developed to simplify the modeling work. Monte Carlo simulations provide good channel prediction for field tests in many scenarios. Then short range communication link performance is studied based on the theoretical vii models, and limitations by power and channel bandwidth are examined. Link budget results are also extended to long range communication links up to 5 kilometers. In this case, atmosphere turbulence becomes pronounced, and thus the intensity fluctuation at the receiver is mathematically modeled. These modeling results can provide insight into the performance tradeoffs and algorithm design for practical NLOS UV communication systems.

“…The model was further extended to accommodate multiple scattering events for sensor network and communication channel modeling [8], [11], [24], similar to backscattering LIDAR [18]. Ding et al proposed a parametric single scattering channel model for both impulse response and path loss [10].…”

AcknowledgmentsI would like to thank all these people who have made this thesis possible and because of whom my graduate experience has been one that I will cherish forever.I would like to express my sincere gratitude to my advisor Prof. Maite Brandt-Pearce for her continuous guidance during my study and research.She is a source of constant encouragement and inspiration and I thank her for believing in me. I could not have imagined having a better mentor for my graduate study. Since UV NLOS communications rely on directed communications, the research explores sectoring the scattering atmosphere into non-overlapping volumes defined by the transmit/receive angles and using this as a multiplex-
