Abstract:

In this contribution, we estimate the spatial diversity order and spatial correlations from channel sounder measurements of doubly-selective vehicle-to-vehicle MIMO radio channels in the 5.2 GHz band. Ivrlac and Nossek [1] have defined a diversity measure of MIMO Rayleigh fading channels which is based on the spatial correlations of the channel. Subsequently, Nabar et al. [2] have shown the existence of an SNR-dependent critical rate for Ricean fading MIMO channels below which reliable transmission with zero outage is achievable. Here, we evaluate and discuss the temporal evolution of the spatial diversity order of doubly-selective vehicle-to-vehicle MIMO radio channels from real-world measurements by extending [1] and [2] to time-variant channels.
