| Abstract: | In order to achieve high spectral efficiency and high energy efficiency for large-scale millimeter-wave multiple-input multiple-output systems, the non-orthogonal multiple access iterative optimization algorithm and cluster head selection algorithm are used to study the hybrid precoding problem in simultaneous wireless information and power transfer scenarios. The simulation results show that the proposed algorithm can achieve higher spectral efficiency and energy efficiency compared with the traditional hybrid precoding algorithm for orthogonal multiple access simultaneous wireless information and power transfer. |

| Keywords: | millimeter wave massive multiple-input multiple-output hybrid precoding non-orthogonal multiple access simultaneous wireless information and power transfer |
