"Measurement-Based Modeling of Vehicle-to-Vehicle MIMO Channels";
in: "IEEE International Conference on Communications",
issued by: IEEE;
Vehicle-to-vehicle (VTV) communications are of interest for applications within trafﬁc safety and congestion avoidance, but the development of suitable communications systems requires accurate models for the VTV propagation channel. This paper presents a new wideband MIMO (multiple-input-multiple-output) channel model for VTV channels based on extensive MIMO channel measurements performed at 5.2 GHz in rural environments in Lund, Sweden. The measured channel characteristics, in particular the non-stationarity of the channel statistics, motivate the use of a geometry-based stochastic channel model (GSCM) instead of the classical tapped-delay line model. We introduce generalizations of the generic GSCM approach and ﬁnd it suitable to distinguish between diffuse and discrete scattering contributions. The time-variant contribution from discrete scatterers is tracked over time and delay using a high resolution algorithm, and our observations motivate their power being modeled as a combination of a deterministic part and a stochastic part. The paper gives a full model parameterization and the model is veriﬁed by comparison of MIMO antenna correlations derived from the channel model to those obtained directly from the measurements.
