Analysis and research on propagation field strength characteristics of non-line-of-sight signal
Published 2024-02-01“…In order to explore the diffraction loss caused by non-line-of-sight (NLOS ) propagation caused by obstacles in the airport communication path, the attenuation characteristics of signal field were studied.Firstly, based on the influence of different terrain environments on signal propagation in ITU-R P.1546, a combined signal field strength model was constructed with Deygout model.Secondly, according to the number of obstacles, the propagation characteristics of the received field strength varying with the height of obstacles were analyzed.The simulation results show that the higher the single obstacle is, the larger the Fresnel zone occupying 0.6F<sub>1</sub> is and the smaller the field strength is.In the dual obstacle path, the obstacle with increased height goes through the process of changing from secondary to main obstacle until only the main obstacle is left, so that the field strength gradually decreases.Thirdly, the relationship between secondary obstacle height and 0.6F<sub>1</sub> Fresnel zone was analyzed for field strength rise.Finally, the minimum threshold of the covered field strength was adjusted to determine whether the receiving device was blocked by obstacles and the signal was shielded.The above research results can provide a reference for simulating the distribution of obstacles in various airport scenarios in the future, and predicting whether the receiver is interfered by obstacles or affects the field intensity coverage.…”

High-precision indoor wireless positioning method based on generative adversarial network
Published 2021-06-01“…Because wireless signals are susceptible to interference during the propagation process, the application of traditional indoor positioning methods in real life is limited.Because location-based fingerprint positioning technology has the advantage of strong universality, it has become a current research hotspot.The number of fingerprint data is an important factor affecting the accuracy of fingerprint positioning, but the cost of collecting a large amount of fingerprint data is large.Therefore, how to use a small amount of fingerprint data to achieve higher positioning accuracy is a difficult point of fingerprint positioning technology.Aiming at this problem, a high-precision indoor wireless positioning method based on generative adversarial network was proposed.Firstly, fingerprint data was collected densely at equal intervals indoors, and the initial fingerprint data set was constructed, the part of the fingerprint data was selected in the initial fingerprint data set, and the generative adversarial network was used to obtain a large amount of fingerprint data from part of the fingerprint data.Then, based on these generated data, a KNN (k-nearest neighbor) model and a random forest model were used for location prediction.Experimental results show that this method can achieve high wireless positioning accuracy based on a small amount of fingerprint data, and the positioning accuracy can reach 15.4 cm.…”

Review and Critique of the Book of Scientific Islamic Economics Theory Building
Published 2017-07-01“…In this book, the author seeks to provide a way for theory building in Islamic economics by combining the teachings of Islam and the scientific method derived from the philosophy of science, but he faces two fundamental problems: Firstly, Islam, in practice, reduces to dos and don’ts, and thus its existential and epistemic propositions are prevented from playing a role in economics; secondly, by accepting experience as the evaluator and the criterion of being scientific, a proposition extends to the empiricism and its weaknesses, of course, the jurisprudential and ideological discussions of the book, especially the subject of constructions are considered as a step forward in the books of Islamic economics. …”
