“…The second term is due to the change of the direction of motion, and the third term is a result of the changing AOA. Note also that for the stationary case, where a 0 = 0, b 0 = 0, and γ n = 0 hold, all three Doppler frequency models described by (9), (11), and (12) reduce to the wellknown expression f n (t) = f n = f max cos(α n − α v ) that is exclusively used for the characterization of the Doppler shift in stationary mobile radio channels. The same statement holds if we observe the channel at t = 0.…”

“…The equation above holds for all given gains c n and timevariant Doppler frequencies f n (t), no matter if we use the exact solution in (9) or the approximations presented in (11) or (12). Analogously, we can compute the time-variant Doppler spread B (2) f (t) of a non-stationary multipath channel with given path gains c n and time-variant Doppler frequencies f n (t) by means of…”

“…The models in [4]- [7] have in common that they originate from stationary plane wave models or sum-of-cisoids (SOC) models in which the time-independent Doppler frequencies have been replaced by time-variant Doppler frequencies. The same procedure has been applied in [8] and [9] to model non-stationary channels.…”

“…In this paper, we propose a class of channel models, referred to as Class B models, that includes the channel models in [4]- [9] as special cases. It is shown that all non-stationary channel models of Class B are inconsistent in the sense that the average Doppler shift of the multipath components is unequal to the average Doppler shift obtained from the time-variant autocorrelation function (ACF) of the complex channel gain.…”

Abstract-This paper is concerned with the consistency of nonstationary multipath fading channels. We introduce conditions under which a channel model is consistent w.r.t. the average Doppler shift and the Doppler spread. The conditions are applied to two classes of non-stationary channel models. The first class, which is termed Class A, is characterized by channel models based on an integral relationship between the path phases and the associated time-variant Doppler frequencies. The second class of models, called the Class B models, emerges from standard sum-of-cisoids (SOC) models by replacing the time-independent Doppler frequencies by time-dependent Doppler frequencies. It is shown that the Class A models fulfil the consistency conditions, while the Class B models are inconsistent. The majority of existing non-stationary channel models with time-dependent Doppler frequencies fall in the Class B category, meaning that these models suffer from a lack of physical soundness. The importance of the paper comes from the fact that it provides guidelines for the design of consistent and physically reasonable non-stationary channel models.

“…The higher the traffic density, the more likely that the case would be non-line-of-sight (NLOS) [16]. Apart from RSGBSMs, MIMO V2V geometry-based street channel model [17], T-junction models [18], and merging lanes on highway model [19] are proposed to study V2V communications. All the aforementioned V2V models just consider the static scatterers on both roadsides, and there are still pressing needs to model the V2V channels considering both the effect of randomly distributed scatterers and non-WSSUS property.…”

In this paper, an extension of spatial channel model (SCM) for vehicle-to-vehicle (V2V) communication channel in roadside scattering environment is investigated for the first time theoretically and by simulations. Subsequently, to efficiently describe the roadside scattering environment and reflect the nonstationary properties of V2V channels, the proposed SCM V2V model divides the scattering objects into three categories of clusters according to the location of effective scatterers by introducing critical distance. We derive general expressions for the most important statistical properties of V2V channels, such as channel impulse response, power spectral density, angular power density, autocorrelation function, and Doppler spread of the proposed model. The impact of vehicle speed, traffic density, and angle of departure, angle of arrival, and other statistical performances on the V2V channel model is thoroughly discussed. Numerical simulation results are presented to validate the accuracy and effectiveness of the proposed model.
