- Abstract
- The next challenge for MIMO radio channel models is to
simulate the time-variant nature of the channel correctly.
Cluster-based MIMO channel models are well suited for
this problem, however they currently lack an accurate parameterization of the time-variant cluster parameters.
In this paper we identify and track clusters from three differentmeasurements conducted in an indoor, a sub-urban,
and a rural environment. The time-variant cluster parameters of interest are: (i) cluster movement, (ii) change of cluster spreads, (iii) cluster lifetimes, and birth and death rates of cluster. We find that clusters show significant movement in parameter space depending on the environment. The spreads of... (More) - The next challenge for MIMO radio channel models is to

In this paper we identify and track clusters from three differentmeasurements conducted in an indoor, a sub-urban,

We find that clusters show significant movement in parameter space depending on the environment. The spreads of individual clusters change rather randomly over their lifetime, with a standard deviation up to 150% of their mean spread. The cluster lifetime is approximately exponentially distributed, however additionally one has to account for long-living clusters coming from the line-of-sight path or from major reflectors. (Less)
