This paper investigates simultaneous wireless information and power transfer (SWIPT) in $K$-user multiple-input multiple-output (MIMO) interference channels. In particular, the power splitting (PS) technique is leveraged at each receiver to divide the received signal into two flows, for information decoding (ID) and energy harvesting (EH), respectively. As a whole system, our objective is to minimize...
This paper focuses on the simultaneous wireless information and power transfer (SWIPT) in coordinated multi-cell networks. In particular, the considered system has a location-aware feature, i.e., the conventional coordinated multi-point (CoMP) information transmission is available to the cell-edge users; meanwhile, the emerging wireless power transmission is available to the cell-center users. Subject...
This paper investigates the beamforming for three- dimensional multiple input multiple output (3D-MIMO) systems with inaccurate channel state information (CSI). From the view of angle-domain, the 3D-MIMO channel is sparse on the high 3D resolution provided by planar antenna array with large number of antenna elements at the base station (BS) in 3D-MIMO systems. Prior knowledge of sparsity is not only...
In this paper, we investigate the simultaneous wireless information and power transfer (SWIPT) in multi-user multiple-input multiple-output (MIMO) interference networks. In this system, each transmitter sends one data stream to its targeted receiver through beamforming, while each receiver divides the received signal into two signal flows via power splitting (PS), for information decoding (ID) and...
