Near-optimal joint selection of transmit and receive antennas for MIMO systems

In this paper, we present a real-time low-complexity joint transmit and receive antenna selection algorithm for MIMO systems. We apply ant colony optimization (ACO) to the joint antenna selection problem. The computational complexity of exhaustive search in this problem grows exponentially with the number of transmit and receive antennas. The proposed ACO for joint antenna selection has a low computational complexity, and its effectiveness is verified through simulation results.
