Microdiversity and Vegetation Influence on Forward Scattering at 60 GHz and 80 GHz
Radek Zavorka, Ondrej Zeleny, Jiri Blumenstein +9
Understanding the impact of vegetation and small-scale antenna movements on signal propagation is important for the design and optimization of high-frequency wireless communication…
Stochastic 3-D Foliage Modeling at 80 GHz: Experimental Validation and Ray-Tracing Simulations
Jiri Blumenstein, Radek Zavorka, Josef Vychodil +10
A stochastic modeling methodology for 3-D foliage is presented, aimed at enhancing ray-tracing simulations. The model supports adjustable stochastic geometry, density, and shape to…
Angularly-Resolved 3D Foliage Modeling and Measurements at 60 and 80 GHz: From Stochastic Geometry to Deterministic Channel Characterization
Jiri Blumenstein, Radek Zavorka, Josef Vychodil +10
In this paper, we show a stochastic approach to generate a 3D model of a foliage, which is then used for deterministic ray-tracing channel modeling. This approach is verified by a…
Comparison of 60 GHz and 80 GHz Vehicle-to-Vehicle Channels Using Delay and Doppler Characteristics
Ales Prokes, Tomas Mikulasek, Josef Vychodil +6
The aim of this paper is to provide a comparison of channel characteristics for vehicle-to-vehicle (V2V) communication at 60 GHz and 80 GHz frequency bands in a high-mobility scena…
Vehicle-to-Vehicle Millimeter-Wave Channel Characterization at 60 and 80 GHz
Radek Zavorka, Tomas Mikulasek, Josef Vychodil +9
This paper presents results from a vehicle-to-vehicle channel measurement campaign conducted in the millimeter-wave (MMW) frequency bands at center frequencies of 60GHz and 80GHz,…
Channel impulse response peak clustering using neural networks
Petr Horky, Ales Prokes, Radek Zavorka +4
This paper introduces an approach to process channel sounder data acquired from Channel Impulse Response (CIR) of 60GHz and 80GHz channel sounder systems, through the integration o…
