“…For example, if the vertical dimension of both scattering volumes in our model approaches zero, i.e., c 1 → 0 and c 2 → 0, then our model reduces to the 2-D model proposed in [13]. By eliminating the scattering volume completely from one link end, i.e., substituting a = b = c = 0, our model reduces to the fixed-to-vehicle (F2V) channel model proposed in [23].…”

“…The Cartesian coordinates of the two mobile nodes, MS 1 and MS 2 are considered at (0, 0, 0) and (d, 0, 0), respectively, where d is the horizontal distance between the MSs. The proposed 3D analytical model is based on some assumptions that are commonly used in the derivation of geometric channel models [7][8][9]13,[17][18][19][20][21], which are listed below:…”

“…In contrast with conventional cellular systems, which have BS antenna heights above or at rooftop levels, the antenna heights of the communicating nodes in a V2V link are typically much lower than the surrounding scatterers such as buildings and trees. This difference in propagation environments has led to numerous investigations into appropriate 2D and 3D models for V2V communication channels, see for example [10][11][12][13][14][15][16]. Among the aforementioned 2D V2V models, in [10], a uniform distribution of scatterers in circular regions is assumed around each MS and the ToA and AoA statistics are investigated.…”

“…Using this model, closed-form expression for the PDF of AoA and an integral formulation for the cumulative distribution function (CDF) of ToA are derived. In [13], a more general 2D elliptical model is proposed for V2V channels by assuming the scatterers to be uniformly distributed within adjustable hollow ellipses around each MS and the PDF of the AoA at each MS is then derived.…”

In vehicle-to-vehicle (V2V) communication scenarios, the antenna heights of the communicating nodes are typically lower than the heights of scattering objects in the vicinity of these nodes such that signal propagation in the elevation plane cannot be ignored. Therefore, it is necessary to consider three-dimensional (3D) space for modeling radio propagation in V2V communication environments. In this paper, the temporal characteristics of a 3D semi-ellipsoid geometrical channel model for V2V communication scenarios is presented by assuming uniform scatterer distribution around the mobile stations (MSs). Using the 3D semi-ellipsoid channel model, closed-form expressions for the joint probability density function (PDF) of the time-of-arrival (ToA) and angle-of-arrival (AoA) in azimuth and elevation planes is derived. A closed-form expression for the marginal PDF of ToA of the received signal is also provided. The proposed analytical results are compared with those obtained from some notable geometric channel models found in the literature.

A geometry-based three-dimensional (3D) novel stochastic channel model for air-to-ground (A2G) and ground-to-air (G2A) radio propagation environments is proposed. The vicinity of a ground station (GS) is modelled as surrounded by effective scattering points; whereas the elevated air station's (AS) vicinity is modelled as a scattering-free region. Characterization of the Doppler spectrum, dispersion in the angular domain and second order fading statistics of the A2G/G2A radio communication channels is presented. Closed-form analytical expressions for joint and marginal probability density functions (PDFs) of Doppler shift, power and angle of arrival (AoA) are derived. Next, the paper presents a comprehensive analysis on the characteristics of angular spread on the basis of shape factors (SFs) for A2G/G2A radio propagation environments independently in both the azimuth and elevation planes. The analysis is further extended to second order statistics of the fading channel; where the behaviour of the level crossing rate (LCR), average fade duration (AFD), auto-covariance and coherence distance for the A2G/G2A radio propagation environment is studied. Finally, the impact of physical channel parameters, such as the mobility of AS, the height of AS, the height of GS and the delay of the longest propagation path, on the distribution characteristics of Doppler shift, angular spread and second order statistics is thoroughly studied.
