Capacity evaluation of measured vehicle-to- vehicle radio channels at 5.2 GHz

Summary, in English

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.
