“…This is because the clipped scattering region is geometrically asymmetric, as illustrated in Figs. 3 and 4, and the number of multi-path components corresponding to the positive and negative Doppler frequencies is unequal [12]. Moreover, it is observed that the PDFs of Doppler frequency gradually increase with an increase in the distance between the MT and MR or the number of reflections.…”

“…In general, the transmission signal from the MT to the MR under multi-bounced propagation paths. However, for the conventional scattering channel models in [5][6][7][8][9][10][11][12][13], they almost concentrated on the single-and doublebounced models. For this we should propose multi-bounced scattering channel model, which can be utilized to accurately describe mobile radio communication environments.…”

“…For example, circular scattering models, ellipse scattering models [5], and asymmetric scattering models [9], which indicate that propagation takes place within the plane joining the tips of the transmitting and receiving antennas. Subsequently, many researchers have observed an angular spreading of the waves in the elevation plane because of the interaction of the waves with street buildings, ground, and other vertically disposed objects [10][11][12][13]. In 2010, Nawaz [10] presented a three-dimensional (3D) scattering model for macrocell environments, with a base station (BS) employing a directional antenna located outside the hemispheroid.…”

“…Furthermore, Jiang [11] derived a generalized 3D scattering channel model for microcell environments, in which the scatterers are assumed to be located around the BS with a uniform distribution. Recently, a 3D ellipsoidal model for the mobile-to-mobile (M2M) radio propagation environments was proposed, in which the most frequent occurrence of the AoA of the received multi-path waves is located around the relative direction at each mobile station (MS) [12].…”

This paper presents a generalized visual scattering channel model for car-to-car (C2C) mobile radio environments, in which an asymmetric directional antenna is deployed at the mobile transmitter (MT). The signals received at the mobile receiver (MR) from the MT are assumed to experience multibounced propagation paths. More importantly, the proposed model first separate the multi-bounced propagation paths into odd-and even-numbered-bounced propagation conditions. General formulations of the marginal probability density functions (PDFs) of the angle-of-departure (AoD) at the transmitter and angle-of-arrival (AoA) at the receiver have been derived for the above two conditions, respectively. From the proposed model, we derive an expression for the Doppler frequency due to the relative motion between the MT and MR, which broadens the research of the proposed visual street scattering channel model. The results show that the proposed model can fit those of the previous scattering channel models and the measurement results for dense urban street environments very well, which validate the generalization of the proposed virtual street channel model.

“…In V2V communication channels, both the transmitter (Tx) and the receiver (Rx) may be in motion and lower than scatterers on surrounding buildings, which is different from conventional fixed-to-mobile (F2M) cellular systems. The performance of V2V propagation channel between Tx and Rx can significantly differ depending on scattering environments around them and whether the link exists line-of-sight (LoS) components owing to buildings, roadside infrastructures, and road bending [4]. V2V channels generally may have contributions from LoS paths, reflections from large stationary and moving objects such as buildings and neighboring vehicles, and a diffuse base from large numbers of small stationary objects in the environment.…”

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.

The system performance of mobile-to-mobile (D2D) cooperative communication has been improved by utilizing spatial modulation (SM) in this paper. The proposed system employs decode and forward (DF) relaying technique along with physical layer network coding (PLNC); hence, it has been named as SM-based decode and forward two-way relay (DFTWR). It enables full-duplex communication thereby enhancing the system efficiency. Information bits are exchanged between the two bidirectional nodes. For two bits of information exchange, the antenna index is conveyed by the least significant bit (LSB) of the data symbol while the most significant bit (MSB) carries the message. The system performance has been investigated by analyzing certain performance metrics like lower and upper bounds of outage probability and average data rate for N--cascaded fading channels. The change in the system performance by varying certain parameters like relative geometrical gain, fading coefficients, and number of cascaded components has also been put forth in this paper. KEYWORDSD2D system, N--cascaded fading channels, outage probability, PLNC, SM INTRODUCTIOND2D communication is a prevalent research topic that can be utilized for mobile ad hoc networks in wireless communication industry. 1 Cascaded fading models are used as a replacement for old classical models in order to provide better accuracy. In D2D communication, relative motion exists between the transmitter and receiver, and both nodes possess low-height antennas, which are located almost at the street level. Scatterers are also present at transmitter and receiver. D2D communication varies from cellular communication in this aspect. The base station antenna in cellular communication is elevated and fixed, thereby being devoid of local scatterers. However, the mobile antenna is at a lower level and is in motion. Traditional channel models are unsuitable for D2D communication as multiple scattering groups are present in D2D communication. 2 Abbreviations: D2D, device to device; PLNC, physical layer network coding; SM, spatial modulation Int J Commun Syst. 2019;32:e3876.wileyonlinelibrary.com/journal/dac
