Abstract

Based on multi-node multi-antenna channel measurements in a multi-wall office environment, we estimate the degree of separation between multiple MIMO links by means of two metrics: the correlation matrix distance and the shadowing correlation. Both nomadic and mobile node scenarios are considered and compared. Empirical models are eventually derived. Our analysis reveals that the average separation between two MIMO links sharing a joint transmitter is usually lower in mobile scenarios than in nomadic scenarios, and is strongly related to the spatial correlation of the individual MIMO links. However, there appears to be no relationship between the correlation matrix distance and the shadowing correlation.
