Comparison of angular and delay spreads between channel measurements and the COST channel model

In English The COST2100 channel model is a reference channel
model which provides dynamic multiple-input multiple-output
channel responses for radio system simulations. In this paper,
channels created by the COST2100 model were compared to
channel measurements in order to understand behaviours of
the model. Model parameters of the COST2100 model were
derived by dynamic double-directional channel measurements
with which the channel realizations from the COST2100 model
were compared. Delay and angular spreads were used as a
simple but important metric for the comparison. Despite a
fundamental difference that the COST2100 model is a geometry-
based stochastic model while the channel measurements are ob-
tained in deterministic environments, the comparison revealed an
acceptable level of agreement for practical channel simulations.
