We present a generic statistical characterization of the vehicle-to-vehicle (V-V) wireless channel by adopting a stochastic modeling approach. Our approach is based on the doubly underspread (DU) property of non-wide sense stationary uncorrelated scattering (non-WSSUS) wireless channels, with V-V channels pertaining to this category. DU channels exhibit explicit frequency and time intervals over which they are approximated as WSSUS. We call these intervals restricted time interval (RTI) and restricted bandwidth (RBW), and variations taking place inside them are characterized as small scale variations. Large scale variations take place outside RTI and RBW. In this paper, we focus on small scale variations, thus, our modeling finds its applicability within RTI and RBW. As practical V-V channels exhibit rapid

“…In these models, the GBSMs are most widely used in V2V communication systems for theoretical analysis of channel statistics and performance evaluation, which can be classified as regular-shaped GBSMs (RS-GBSMs) [5][6][7][8][9][10] and irregular-shape GBSMs [11,12], mainly depending on whether scatterers are located on regular shapes or irregular shapes. The authors of [5][6][7][8] presented RS-GBSMs consisting two-ring, two-cylinder, and one ellipse models.…”

“…In [6,7], the authors proposed two-dimensional (2D) RS-GBSMs; they neglect signal variations and spatial diversity in the vertical plane. Therefore, 3D two-cylinder and multiring RSGBSMs were developed for wideband nonisotropic MIMO V2V channels in [8,9]. Even though many 3D V2V channel models have been proposed over the past few years, they all assumed that the elevation angle and the azimuth angle are completely independent, which also does not adapt to all realistic vehicular scenarios.…”

We develop a novel three-dimensional (3D) cluster-based channel model for vehicle-to-vehicle (V2V) communications under the scenarios of urban street scattering environments. The proposed model combines the flexibility of geometrical channel models with the existing state-of-the-art 3D V2V models. To provide an accurate representation of specific locations and realistic V2V fading environments in a computationally manageable fashion, all clusters are divided into three groups of use cases including "ahead," "between," and "behind" clusters according to the relative locations of clusters. Using the proposed V2V model, we first derive the closed-form expressions of the channel impulse response (CIR), including the line-of-sight (LoS) components and cluster components. Subsequently, for three categories of clusters, the corresponding statistical properties of the reference model are studied. We additionally derive the expressions of the 3D space-time correlation function (STCF), the autocorrelation function (ACF), and 2D STCF. Finally, comparisons with on-road measurement data and numerical experiments demonstrate the validity and effectiveness of the proposed 3D cluster-based V2V model.

“…Therefore, three dimensional (3-D) channel models should be developed for massive MIMO systems. Extensive conventional 3-D MIMO models can be found in the literature such as the twin-cluster MIMO model [34], the COST 2100 model [35], [36], 3-D extension of the WINNER model [37], 3-D double-directional radio model [38], and 3-D MIMO vehicleto-vehicle channel model [39]. In this paper, we will extend the twin-cluster MIMO model in [34], where a cluster is divided into two representations of itself (one at the transmitter and the other at the receiver), by incorporating the spherical wavefront assumption, cluster evolution on the time and array axes, and 3-D cluster properties to capture massive MIMO channel characteristics.…”

Abstract-This paper proposes a novel theoretical non-stationary three dimensional (3-D) wideband twin-cluster channel model for massive multiple-input multiple-output (MIMO) communication systems with carrier frequencies on the order of gigahertz (GHz). As the dimension of antenna arrays cannot be ignored for massive MIMO, near field effects instead of far field effects are considered in the proposed model. These include the spherical wavefront assumption and a birth-death process to model non-stationary properties of clusters such as cluster appearance and disappearance on both the array and time axes. Their impacts on massive MIMO channels are investigated via statistical properties including correlation functions, condition numbers, and angular power spectra. Additionally, the impact of elevation angles on correlation functions is discussed. A corresponding simulation model for the theoretical model is also proposed. Finally, numerical analysis shows that the proposed channel models are able to serve as a design framework for massive MIMO channel modeling.Index Terms-Massive MIMO, 3-D twin-cluster channel model, spherical wavefront, non-stationarity, birth-death process.
