摘要:Simultaneous wireless information and power transfer (SWIPT) and interference alignment (IA) are two emerging techniques in energy harvesting and interference management for the next generation wireless networks, respectively. Although many studies have focused on SWIPT and IA, the conjunction of these two techniques is largely ignored, which should be noted to reuse the interference as energy for harvesting. In this paper, we jointly study SWIPT and IA in the multiuser MIMO system to realize energy harvesting and interference management simultaneously and effectively. Specifically, antenna selection (AS) based SWIPT scheme is proposed and analyzed for IA networks. Furthermore, power allocation (PA) for multiple data streams is designed to further improve its performance, and the closed-form solution can be obtained by Lagrange duality method. In addition, given the constrained number of antennas, another scheme called power splitting (PS) based SWIPT is utilized, where PA is also considered and formulated as a joint optimization problem. Simulation results are presented to show the superiority of the proposed schemes.
