Investigation of multi-link spatial correlation properties for cooperative MIMO channels

In this paper, a comprehensive investigation of multi-link spatial correlation properties for cooperative multiple-input multiple-output (MIMO) wireless channels is presented. The impact of interested and important parameters, e.g., local scattering density (LSD) and environment-related parameters, on multi-link spatial correlation properties is completely investigated. Some interesting observations are found and useful conclusions are made. They are helpful for better understanding cooperative MIMO channels and for setting up more purposeful measurement campaigns.
