Journal ArticleDOI
Radio Channel Modeling for UAV Communication Over Cellular Networks
Rafhael Amorim,Huan X. Nguyen,Preben Mogensen,Istvan Z. Kovacs,Jeroen Wigard,Troels B. Sorensen +5 more
TL;DR: The results show that path loss exponent decreases as the UAV moves up, approximating freespace propagation for horizontal ranges up to tens of kilometers at UAV heights around 100 m.
Proceedings ArticleDOI
From antenna spacings to theoretical capacities - guidelines for simulating MIMO systems
TL;DR: With the help of the established relations, correlated flat-fading MIMO channels are generated, whose capacity performance and effective degrees of freedom (EDOF) are investigated for two power allocation schemes, water-filling and uniform.
Journal ArticleDOI
Experimental analysis of the joint statistical properties of azimuth spread, delay spread, and shadow fading
TL;DR: All essential parameters required for the implementation of a simulation model considering the joint statistical properties of the local azimuth spread, the local delay spread, and shadow fading are provided.
Proceedings ArticleDOI
Spatial channel characteristics in outdoor environments and their impact on BS antenna system performance
TL;DR: The power azimuth spectrums impact on a conventional beamformer ability to suppress interfering users is investigated and an analytical expression for the spatial correlation function is derived based on the Laplacian model.
Journal ArticleDOI
Power azimuth spectrum in outdoor environments
TL;DR: From extensive 2D channel measurements it is found that the shape of the power azimuth spectrum at the base station in outdoor environments is accurately described by a truncated Laplacian function in both rural and urban environments.
