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

• 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.
