As the operating frequency was increase from 1800-2600 MHz, the path loss also increases due to decrease in antenna aperture and decrease in radio signal wavelength. Moreover, we observed a noticeable reduction in path losses as both the transmitter antenna height and receiver antenna height were...
摘要: A new method based on feed-forward neural networks for propagation loss prediction in urban environment is introduced in this paper. This method is particularly suited for application in mobile network planning.关键词: backpropagation feedforward neural nets mobile radio radiowave propagation ...
Here, clearance(τi) is the clearance of the trajectory τi as per the choice of modelling. Similarly, for smoothness, given by Eq. (18.5). (18.5)smoothnessΓ=∑i=1nsmoothnessτin The overall measure may be a weighted addition of all measures. ...
histologic features relevant for disease progression. This first proof of concept shows that NGM-based data can be used to make histopathology analysis quantitative, capturing more subtle changes which better reflect the biological reality of disease progression and modelling disease progression relevant ...

signal traces. The issue of crosstalk further deviates the modelling of real-world system board traces from the idealities of the lossless LC transmission line, where closely routed signal traces can become attackers on their neighboring signal traces and significantly impact the timing and signal ...

each robot has a differential drive and its shape can be bounded by a disk with a limited radius. For simplicity and without loss of generality, a point robot is considered in the polygonal domaincreated by enlarging the original map by the radius of the disk, and all free space is reacha...
The formulated path loss models can be used to predict the coverage area and signal quality of millimetre-wave communication systems at these frequencies and locations. Article Highlights: Millimetre-waves path loss in Nigerian cities varies significantly with frequency, environmenta...
