Abstract
This paper studies simultaneous wireless information and power transfer in a K-user multiple-input multiple-output interference channel. A new scheme jointly designing interference alignment (IA) and wireless energy harvesting is proposed. Firstly, the character of each receiver is determined according to the maximum achievable rate and maximum harvested power. The receiving users are used as either energy harvesting (EH) users or information decoding (ID) users, where EH users are used to harvest energy, and ID users are used to transmit information. Secondly, the double-objective problem is established by maximizing both the total power harvested by EH users and the total signal-to-interference-noise ratio (SINR) of the ID users. The problem is solved by the weighted sum method. Moreover, the transmit precoding matrices and the receive interference suppression matrices are solved by iterative optimization algorithm based on a complete IA constraint (IOA-CIA). Simulation results show that the proposed IOA-CIA algorithm provides higher sum rate and harvested power than the existing algorithm. |
