Universal Kriging for Accurate Shadow Fading Modeling in LOS/NLOS Conditions

IEEE Open Journal of Antennas and Propagation
Traditional path loss (PL) models often fail to capture the spatial characteristics of wireless channels in environments combining line-of-sight (LOS) and non-line-of-sight (NLOS) conditions, where shadow fading exhibits clear spatial non-stationarity ...

Propagation and narrow cylindrical antennas for non-line-of-sight links

, 2020
Marconi’s century-old commercialization of wireless has grown to billions of radio links. In cities there can be thousands of cellular base stations, usually mounted on buildings, to link millions of terminals, and there are many WiFi devices in homes and offices.

Measurement and analysis on channel large scale fading characteristics of conference room at 15 GHz

Dianxin kexue, 2016
The shortage of traditional mobile cellular band makes the development of higher frequency paid more and more attention. The time domain measurement system based on PN sequence was used to measure propagation characteristics of the line-of-sight（LOS）and ...
