Abstract :
The COST 2100 channel model has introduced the concept of common clusters to model multi-link MIMO characteristics. In this paper, a ray launching tool is used to analyze multi-ink propagation properties in an outdoor scenario at 300 MHz. It is shown that in a multi-link propagation scenario there are shared scatterers among the different links, which reflects the physical existence of common clusters. The identification of common clusters in the measured outdoor scenario is discussed with respect to the shared scatterers and distances between the scatterers and multiple mobile stations (MSs).We observe that, as the MS separation distance is increasing, the number of common clusters is decreasing and the inter-link correlation is decreasing as well. Multi-link MIMO simulations are also performed using the COST 2100 channel model with extracted common cluster parameters. It is shown that the common clusters can represent multi-link properties well with respect to inter-link correlation and sum rate capacity.
