Abstract :
The combination of full-duplex (FD) technique and multiple-input multiple-output (MIMO) technique significantly improves spectral efficiency, while at the same time it increases hardware cost and complexity. Antenna selection is an effective approach to mitigate this problem. In this paper, the transmit antenna selection algorithm for FD bidirectional MIMO system is studied. At first, the system model and the capacity of bidirectional communication is formulated. Then, an antenna selection algorithm based on greedy approach for FD bidirectional MIMO system is proposed, it can achieve almost the same system capacity as the exhaustive search algorithm with lower computational complexity. Extensive simulations are conducted to support the excellent performance of the proposed antenna selection algorithm, and the capacity of the proposed algorithm under different signal-to-noise ratio (SNR) and interference-to-noise (INR) is analyzed.
