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…
Comparative analysis of clustering methods for power delay profile in MMW bands and in-vehicle scenarios
Radek Zavorka, Ales Prokes, Josef Vychodil +6
The spatial statistics of radio wave propagation in specific environments and scenarios, as well as being able to recognize important signal components, are prerequisites for depen…
Synthesis of omnidirectional path loss model based on directional model and multi-elliptical geometry
Jaroslaw Wojtun, Cezary Ziolkowski, Jan M. Kelner +7
Millimeter wave (mmWave) technology offers high throughput but has a limited radio range, necessitating the use of directional antennas or beamforming systems such as massive MIMO.…
Variability of radio signal attenuation by single deciduous tree versus reception angle at 80 GHz
Jaroslaw Wojtun, Cezary Ziolkowski, Jan M. Kelner +7
Vegetation significantly affects radio signal attenuation, influenced by factors such as signal frequency, plant species, and foliage density. Existing attenuation models typically…
Spectral efficiency for mmWave downlink with beam misalignment in urban macro scenario
Jaroslaw Wojtun, Cezary Ziolkowski, Jan M. Kelner +7
In this paper, we analyze the spectral efficiency for millimeter wave downlink with beam misalignment in urban macro scenario. For this purpose, we use a new approach based on the…
