Space­Time Coding Over Correlated Fading Channels With Antenna Selection
Israfil Bahceci, Yucel Altunbasak, Senior Member, IEEE, and Tolga M. Duman, Senior Member, IEEE
Abstract--In a previous paper by Bahceci et al., antenna
selection for multiple-antenna transmission systems under the
assumption that the subchannels between antenna pairs fade in-
dependently was studied. In this paper, the performance of such
systems when the subchannels experience correlated fading is
considered. It is assumed that the channel-state information (CSI)
is available only at the receiver, the antenna selection is performed
only at the receiver, and the selection is based on the instantaneous
received signal power. The effects of channel correlations on the
diversity and coding gain when the receiver system is a subset of
the antennas are quantified. Theoretical results indicate that the
correlations in the channel do not degrade the diversity order,
provided that the channel is full rank. However, it does result in
some performance loss in the coding gain.
