Optimal Antenna Selection Designs for Coupled MIMO Systems
We consider the impact of antenna mutual coupling on receive antenna selection systems. Prior work on selection with mutual coupling has not considered the effects of the inactive (i.e., unselected) antenna terminations and spatial noise correlation. In this work, we show that the presence of inacti...

| Summary: | We consider the impact of antenna mutual coupling on receive antenna selection systems. Prior work
on selection with mutual coupling has not considered the effects of the inactive (i.e., unselected) antenna
terminations and spatial noise correlation. In this work, we show that the presence of inactive antennas
can profoundly alter system performance when the antennas are strongly coupled. We also propose a new
antenna selection technique that seeks to exploit coupling to improve performance. Simulations suggest
that the new technique can significantly outperform traditional selection when coupling is present. |
