Application of MIMO technology in cooperative
communications results in many advantages such as high data
rates, better reliability and coverage. A drawback of MIMO
technology is its high computational complexity and high cost
because it uses more antennas and RF chains. A remedy for
this drawback is antenna selection technology. This technology
attempts to select the best antenna based on the channel state
information (CSI). Some transmit antenna selection methods
have been proposed in the literature for MIMO systems.
Suboptimal antenna selection has been proposed to reduce the
required computation to determine the best antenna as well.
Optimal and suboptimal antenna selection has not been
investigated perfectly for MIMO relay systems. In this paper
we propose a suboptimal transmit antenna selection for MIMO
relay system which has low computational complexity and we
compare its performance with optimal transmit antenna
selection and other suboptimal transmit antenna selections.
