Abstract
In a wireless multiple-input multiple-output
(MIMO) system, transmit antenna selection is an effective
means of achieving good performance with low complexity. We
consider spatial multiplexing with linear receivers, and equal
power and equal rate allocation over different selected transmit
antennas in order to reduce feedback overhead. Under these
constraints, we address the problem of statistical multimode
transmit antenna subset selection to improve the capacity
of spatially correlated MIMO fading channels. In particular,
we first derive an analytical closed-form expression for the
expectation of the lower bound on the capacity using the
smallest eigenvalue distribution of a Wishart matrix. Then,
we propose a transmit antenna subset selection criterion of
maximizing this average lower-bound capacity.
