Applying spatial mode switching in channel adaptive MIMO systems promises to achieve high spectral efficiencies in practical system setups. Several studies have pointed out significant performance gains obtained in realistically modeled channel scenarios. The authors have conducted channel measurements with the Berlin LTE-Advanced Testbed operated in the city center of Berlin and used these for the performance evaluation of a spatial mode switching concept that has previously been evaluated in a link- and system-level simulation environment. Results from measurements and simulations are shown to be in close correspondence.
