Line of sight is a vital factor inwirelesscommunication. Some forms of wireless transmission are completely blocked if anything comes between the transmitter and receiver. Other forms of transmission can penetrate less dense objects, like walls and building, but are blocked by large objects, like mo...
In dynamic space networks, achieving high precision and fast initial pointing of the optical line of sight (LOS) is the key goal in developing this technology. It is the premise and basis of realizing optical LOS capture. Based on the composition and working principle of space optical networkin...
Line of sight (LoS) is a type of propagation that can transmit and receive data only where transmit and receive stations are in view of each other without any sort of an obstacle between them. FM radio, microwave and satellite transmission are examples of line-of-sight communication. Advertise...
This paper presents an approximate closed-form model of non-line-of-sight (NLOS) ultraviolet (UV) single-scatter propagation in noncoplanar geometry for tr... Z Yong,H Xiao,W Zhang,... - International Icst Conference on Communications & Networking in China 被引量: 6发表: 2012年 Simplified ...
Statistics-based inter-subchannel interference (ICI) mitigation schemes are developed for orthogonal frequency division multiplexing (OFDM) transmission over high-mobility channels with line-of-sight components. By utilizing the channel statistics, we develop the Wiener filtering in the downlink and the tr...
It should be obvious that any claims for maximum distance are probably assuming line-of-sight transmission, which is rarely the case. Objects such as walls, floors, metal panels, pipes and electrical wiring can greatly decrease this distance. In situations of low signal strength, the 802.11b ...
UWB室内定位算法的误差主要来源于NLOS(Non Line Of Sight,非视距)信号,针对基于特征的NLOS识别方法需要手动提取特征且识别效果较差这一问题,有学者提出了CNN(Convolutional Neural Network,卷积神经网络)、FCN(Full Convolutional Network,全卷积神经网络)和ResNet(Residual Network,残差网络)等不同的神经网络识别NLOS信号...

Line-of-sight (LOS) link planning condition has been observed to have effects on the atmospheric factor which cause crucial signal loss. The main objective of the planning was to improve a set of a link using point to point condition to assist the performance in emerging its strategy for han...
