Three-dimensional localization under severely obstructed NLOS environment by Zhu XIAO, Jie CHEN, Dong WANG, Xiao-hong LI, Ren-fa LI

“…In the severely obstructed NLOS(non-line-of-sight)environment,obstacles between the UN(unknown node)and RS(reference station)made the DP(direct path)undetectable.It greatly restricted the application of wireless localization method.A three-dimensional localization scheme,which utilized the distance and orientation information of single-bounce signal,was proposed to evade the DP blocking effect in three-dimensional NLOS environment.Within the proposed localization scheme,three-dimensional spatial location relationship among the RS,UN and scatterers was proven.Anoptimization algorithm based on least mean square was proposed and the mathematical solution to the position relationship was derived.Furthermore,the performance of algorithm is studied by using RMSE(root mean-square error)analysis.Through Monte-Carlo simulations,how distance and orientation deviation of three-dimensional localization frame affect performance of algorithms is examined.It is also demonstrated that the analytical results closely match the simulations,which verifies the effectiveness of the proposed three-dimensional NLOS localization algorithm.…”

Design of amplifying information metasurface for enhancing signal coverage by Lijie WU, Hanqing YANG, Qiang CHENG, Tiejun CUI

“…Traditional information metasurfaces can be used in wireless relay systems to control the propagation direction of electromagnetic waves due to their capability to control the amplitude and phase.However, owing to the lack of signal amplification function, these metasurfaces have a limited operating distance.Thus, a large size of metasurfaces is usually demanded to realize the signal coverage of dead zones.To solve this problem, an amplifying information metasurface was designed to realize the 2 bit phase manipulation and signal amplification function within the broad band from 2.7 to 3.1 GHz.Furthermore, a power dividing and combining network was introduced to combine the 1×8 metasurface elements into an array with only one amplifier, which greatly reduced the number of amplifiers, the hardware cost, and the power consumption.The simulation results indicate that the array can realize beamforming and signal amplification over a broad band.Therefore, the proposed amplifying information metasurface array may find important applications in wireless relay systems and provide a new solution to enhancing the signal coverage and reducing the size of the metasurface array.…”

Analysis and Optimization of Tooth Surface Contact Parameter of ZC1 Worm Gear by Song Lijuan, Ji Weixi, Xie Jian, Wang Yu

“…Based on the meshing theory of ZC1 worm gear pair,the tooth surface contact parameters are analyzed by using MATLAB.The results show that the axial module,center distance,lead angle,radius of arc tooth profile of grinding wheel have great influence on tooth surface contact parameters.In general,the center distance is selected in the beginning of design,so the axial module,lead angle,radius of arc tooth profile of grinding wheel are selected as design variable.For improving the meshing performance of worm gear pair,taking the induced normal curvature and lubrication angle as objective function,and combining with the constraints of top thickness of worm,top thickness of worm wheel and undercutting,the optimum mathematical model is established.The improved particle swarm algorithm is adopted as optimization algorithm and the results show that the optimized lubrication angle is larger and induced normal curvature is smaller.The meshing performance of worm gear pair is improved effectively.…”
