“…A similar rationale was also deployed in [49, Ch. (7)], which has been validated by numerous measurement campaigns of fixed wireless channels (wireless channels with static Tx and Rx and scatterers' mobility as the only source of temporal variability), see related references discussed in [65].…”

“…Alternative suitable PDFs, were shown to be the Nakagami-m (with 1/ 2 m  ), the gamma and the lognormal. In, [65] the ACF due to scatterers' mobility was determined based on the relevant scattered power. This is different from considering scatterers' velocity distributions (see, e.g., [66] and [67]) and directly applying them to model () S uS pu as in [47].…”

“…Such physical behaviour is guaranteed by the PDF of equation (31), as well as by the other alternative PDFs considered in [65]. Thus, it is essential to model the multipath power distribution over the velocities, rather than the velocity distribution itself.…”

“…More specifically, from equation (A6) in Appendix, we see that if w decreases, 2 W (the second moment of the Weibull random variable used to describe () S uS pu) increases, making the scatterers' mobility more intense because the mean value and variance of S u increase (see [65], [69, Table ( .

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

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
