【摘要或目錄】：
This paper treats multiple-input multiple-output
(MIMO) antenna subset selection employing space-time coding.
We consider two cases differentiated based on the type of channel
knowledge used in the selection process. We address both the
selection algorithms and the performance analysis. We first
consider the case when the antenna subsets are selected based
on exact channel knowledge (ECK). Our results assume the
transmission of orthogonal space-time block codes (with emphasis
on the Alamouti code). Next, we treat the case of antenna subset
selection when statistical channel knowledge (SCK) is employed
by the selection algorithm. This analysis is applicable to general
space-time coding schemes. When ECK is available, we show that
the selection algorithm chooses the antenna set that maximizes
the channel Frobenius norm leading to both coding and diversity
gain. When SCK is available, the selection algorithm chooses the
antenna set that maximizes the determinant of the covariance
of the vectorized channel leading mostly to a coding gain. In
case of ECK-based selection, we provide analytical expressions
for average SNR and outage probability improvement. For the
case when SCK-based selection is used, we derive expressions
for coding gain. We also present extensive simulation studies,
validating our results
