Sammanfattning

Reliability in Ricean multiple-input-multipleoutput
(MIMO) channels is crucial for safety-related vehicle-tovehicle
(V2V) applications. In Ricean channels, there is a signalto-
noise ratio-dependent critical data rate below which signaling
with zero outage is possible. The link will be more reliable the
higher this critical data rate is. We present results of spectral
efficiency and outage probability from channel sounder
measurements of V2V MIMO radio channels in the 5.2 GHz
band. Our results show that MIMO channels with higher spatial
correlation lead to lower ergodic capacity and a reduced critical
data rate. However, for fixed output power the temporal
evolution of the ergodic capacity and critical data rate shows that
the channel with the strongest line of sight (LoS) component also
has the highest capacity.
