“…Here, the channel non-stationarity is estimated from the time variation of the Doppler spread [47]. The stationary interval is defined as the maximum time duration within which the relative error of Doppler spread beyond a certain threshold, i.e.,…”

“…The premise of characterizing the non-stationarity is to determine the size of the region in which the stationary assumption holds. Instead of using the WSS region in which the first-and second-order statistical moments are timeinvariant, we use the term quasi-stationary region (or quasistationarity region) similar to the definitions in [13]- [15]. The quasi-stationary region characterizes the region in which the statistics of channel are similar enough compared to the statistics of the neighboring channel so that the channel can be approximately considered to be stationary [13].…”

The quasi-stationary region characterizes the region in which the statistics of channel are similar enough compared to the statistics of the neighboring channel so that the channel can be approximately considered to be stationary [13]. It should be noted that the WSS assumption is stricter than the quasistationary condition according to their definitions.…”

“…In particular, wide-sense stationary uncorrelated scattering (WSSUS) models, which are a subset of the category of random LTV systems, are the most common in the literature. As well, more recent work in this field has focused on nonstationary LTV communications channels [5][6][7], of which vehicle-to-vehicle (V2V) communication is a prime example [8]. A separate set of models that are distinct, but can be related to Bello's LTV theory are the Clarke/Jakes Doppler spectrum class of models [9,10], originally only applicable for flat fading (i.e., where the symbol time is much larger than the multipath delay spread).…”
