—Due to high mobility in multipath propagation environments, vehicle-to-vehicle (V2V) channels are generally time and frequency variant. Therefore, the criteria for wide- sense stationarity (WSS) and uncorrelated scattering (US) are just satisfied over very limited intervals in the time and frequency domains, respectively. We test the validity of these criteria in measured vehicular 60 GHz millimeter wave (mmWave) channels, by estimating the local scattering functions (LSFs) from the measured…

Non-WSSUS Vehicular Channel Characterization at 5.2 GHz - Spectral Divergence and Time-Variant Coherence Parameters

This work characterize the spectral divergence of the local scattering function (LSF) sequence in order to assess the non-WSSUS characteristics in different scenarios and finds that the vehicle-to-vehicle channels violate the wide-sense stationarity much stronger than the US assumption.

The (in-) validity of the WSSUS assumption in vehicular radio channels

It is proved that the fading process in vehicular communications is strongly non-WSS, which agrees with results previously reported in the literature.

Characterization of Quasi-Stationarity Regions for Vehicle-to-Vehicle Radio Channels

We analyze the nonwide-sense-stationarity (nonWSS) of vehicle-to-vehicle (V2V) radio channels using three metrics: 1) the correlation matrix distance (CMD); 2) the wideband spectral divergence (SD);

Position-Specific Statistics of 60 GHz Vehicular Channels During Overtaking

It is demonstrated that large overtaking vehicles boost the mean receive power by up to 10 dB and the analysis of the small-scale fading reveals that the two-wave with diffuse power (TWDP) fading model is adequate.

Non-Stationary Narrowband MIMO Inter-Vehicle Channel Characterization in the 5-GHz Band

Measurements and models of 30 narrowband multiple-input-multiple-output (MIMO) vehicle-to-vehicle (V2V) radio propagation channels at 5.3 GHz found the large-scale fading was found to be lognormally distributed, whereas the small-scale fades was characterized by the flexible Weibull distribution.

Measured delay and Doppler profiles of overtaking vehicles at 60 GHz

We report results from real-world millimetre wave vehicle-to-vehicle channel measurements carried out in an urban street environment, down-town Vienna, Austria. Channel measurements have been

The local scattering function (LSF) and the channel correlation function (CCF) are introduced and shown to characterize, respectively, the mean power and the correlation of non-WSSUS scatterers.

Correlation matrix distance, a meaningful measure for evaluation of non-stationary MIMO channels

It is shown that changes in the spatial structure of the channel corresponding to high values in the CMD also show up as a significant reduction in performance of the considered MIMO transmission scheme, and stationarity can therefore not always be assumed for indoor M IMO radio channels.

Spatial Variation Analysis for Measured Indoor Massive MIMO Channels

The characteristics for massive MIMO channels in an indoor hall scenario at 6-GHz in both line of sight (LOS) and non-LOS (NLOS) conditions are investigated and fluctuations are modeled, where the spatial variation phenomenon was clearly observed over the large-scale antenna array.
