Multi-User Holographic Communications via Channel Operator Diagonalization

Year: 2025

Type: article

Abstract: This paper investigates a multiuser Holographic Multiple-Input Multiple-Output (MIMO) system, where a continuous surface transmitter communicates with multiple dipole receivers. The channel is diagonalized by selecting an optimal basis for both the transmitter and receivers, with the complexity scaling linearly with the number of users. The spectral efficiency of the proposed Holographic MIMO (HMIMO) system is analyzed and compared to that of a conventional fully-digital MIMO system under additive white Gaussian noise. Results indicate that HMIMO outperforms the MIMO system in terms of spectral efficiency, unless an unfeasible number of RF chains is employed.
