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.…
Power angular spectrum versus Doppler spectrum -- Measurements and analysis
Jan M. Kelner, Cezary Ziolkowski, Michal Kryk +9
In this paper, we present an empirical verification of the method of determining the Doppler spectrum (DS) from the power angular spectrum (PAS). Measurements were made for the fre…
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…
