On the Practicability of Airborne MIMO Communication

■ Promising MIMO gain factors also for air-to-ground scenarios ■ Best channel conditions for small number of antennas and moderate distances ■ Air-to-ground and air-to-air similarity: Best results (gain, condition, numerical range) for moderate distances and small number of antennas ■ Numerical range of channel matrix elements increases with number of antennas
