Exploiting Constructive Mutual Coupling in P2P MIMO by Analog-Digital Phase Alignment
2017
IEEE Transactions on Wireless Communications
In this paper, we propose a joint analogdigital (A/D) beamforming scheme for the point-to-point multiple-input-multiple-output system, where we exploit mutual coupling by optimizing the load impedances of the transmit antennas. Contrary to the common conception that mutual coupling strictly harms the system performance, we show that mutual coupling can be beneficial by exploiting the concept of constructive interference. By changing the value of each load impedance for the antenna array based
