Abstract :
The paper discusses several practical issues pertaining to the implementation and operation of multiple-input multiple-output (MIMO) systems. The presentation focuses on signal coupling in integrated RF front ends and closely-spaced antennas, the behavior of realistic channels with practical antenna geometries, and important considerations relating to channel estimation and feedback. These issues are explored using a combination of detailed modeling and simulation, channel measurements, and system implementation using a real-time MIMO communication platform.
