DFT-based Hybrid Antenna Selection Schemes for spatially correlated MIMO channels
Publikation/Tidskrift/Serie: 14th IEEE Proceedings on Personal, Indoor and Mobile Radio Communications, PIMRC 2003.
We address the antenna subset selection problem in spatially correlated MIMO channels. To reduce the severe performance degradation of the traditional antenna selection scheme in correlated channels, we propose to embed DFT operations in the RF chains. The resulting system shows a significant advantage both for diversity schemes and for the capacity of spatial multiplexing, while requiring only a minor hardware overhead.
