This paper considers a joint antenna selection method in amplify-and-forward (AF) relay networks where the source, relay and destination terminals are all equipped with multiple antennas. The fact that the system's full diversity can be maintained by antenna selection at each terminal makes it a promising solution to reduce the hardware complexity of multiple-input multiple-output (MIMO) terminals...
This paper considers a joint antenna selection method in amplify-and-forward (AF) relay networks where the source, relay and destination are all equipped with multiple antennas. Since the exhaustive search for antenna subset selection is computationally prohibitive, a low-complexity near-optimal joint antenna selection algorithm based on a constrained cross entropy optimization (CCEO) method is proposed...
