In this paper we derive a non-line-of-sight (NLOS) path loss model between low-height terminals in rectangular street grid environments. With the Uniform Geometrical Theory of Diffraction, the path loss due to diffraction and scattering at corner edges is calculated for 1-Turn NLOS and 2-Turn NLOS links. In particular, we consider the case that 2-Turn NLOS links have multiple propagation route paths...
In this paper, we investigate multipath azimuthal distribution characteristics between terminals considering for mobile-to-mobile communication scenarios in urban street canyon environments. We carried out channel measurement campaigns on 3.7GHz frequency band at three sites in Seoul, Korea. The root mean square (r.m.s.) angular spread characteristics are analyzed with results of their distribution...
This paper presents line-of-sight (LoS) path loss characteristics for low-antenna links in urban street environments to account for propagation channels in mobile-to-mobile direct communications. The key variables, from the perspective of horizontal and vertical planes of such environments, are street width and surrounding building height. In this paper, we investigate the effects of the environmental...
In this paper, a new path-morphology concept is introduced and the method of classification for wave-propagation environments is proposed based on the pathmorphology concept. The values of relevant parameters in MIMO channels are presented and their validity was also discussed. Since we can see the clear tendency of the parameter values for difference path-morphologies, it can be concluded that the...
