It was shown recently that mutual coupling effectively decomposes otherwise spectrally-identical spatial modes of an antenna array into spectrally non-identical eigen-modes. We shall use Shannon's information theory and Fano's broadband matching theory to develop optimal transceiver designs for a compact broadband MIMO system. It will be shown that in the presence of channel state information, optimal transmit power allocation and matching characteristic follow a mutual space-frequency water-pouring solution.}, booktitle={2012 ieee international conference on communications (icc)}, author={Taluja, P.

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.}, journal={INTERNATIONAL JOURNAL OF ANTENNAS AND PROPAGATION}, author={Taluja, Pawandeep S. and Hughes, Brian L.}, year={2012} }

However, compact arrays offer a unique advantage in that mutual coupling can be exploited to improve the system performance. Previous studies on selection with coupling have not considered the effects of the inactive-antenna terminations and lack detailed transceiver modeling. In this work, we present a communication-theoretic analysis and design of antenna selection systems for compact transceivers. We also propose a simple parasitic antenna selection technique that can significantly outperform traditional selection when coupling is present.}, booktitle={2012 ieee international conference on communications (icc)}, author={Taluja, P.
