“…The spatial and temporal characteristics of the multipath signals play an important role in M2M communication channel modeling. The geometrically-based channel models in M2M communication environment can be traced back from two-dimensional (2D) circular models [1][2][3][4][5] and 2D elliptical models [6,7] to three-dimensional (3D) channel models [8][9][10]. For reader's convenience, we discuss only those 2D and 3D channel models that especially focus on the angle-of-arrival (AoA) and time-of-arrival (ToA) of the multipath signals in M2M communication environment.…”

In this paper, we develop a three-dimensional geometrical channel model for mobile-to-mobile (M2M) communication environment. The proposed model combines most of the existing two-dimensional (2D) and three-dimensional (3D) geometrical channel models for M2M and fixed-to-mobile (F2M) communication channels into one generalized model. Using the proposed model, closed-form expressions for the joint probability density function (PDF) of angle-of-arrival (AoA) and time-ofarrival (ToA) in azimuth and elevation planes are derived. These results are then verified by simulations and available field measurements. Furthermore, comprehensive comparisons of the proposed channel model are carried out with the existing 2D and 3D channel models in the literature, which show that many notable geometrical channel models in M2M and F2M communication environments become the special cases of our proposed generalized 3D geometrical channel model by adjusting corresponding channel parameters. Consequently, the proposed 3D channel model can be taken as a useful tool for modeling mobile ad hoc networks (MANET), Vehicular Ad hoc Networks (VANET) and Intelligent Transportation Systems (ITS).

“…Our proposed model, with appropriate selection of its parameter values, contains many 2D models [9,10,12] and 3D models [20][21][22] as special cases. 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].…”

“…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.…”

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.

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
