“…However, only the BS was considered to be equipped with dual-polarized antennas. In [12], [13], a 3D geometrical model was proposed for dual-polarized MIMO systems, in which it was shown that polarized MIMO exhibits higher capacity performance and robustness when considering Ricean channels.…”

“…The users retrieve their messages from the recovered superimposed data that was assigned to the group that they belong to. However, the messages recovery depend on the type of precoder that is employed at the BS, i.e., the precoding vector can be formulated either as (12) or as (13), and this is further detailed next.…”

“…Such strategy enables the design of compact massive arrays with very low correlation between orthogonal antenna elements. In addition to the space efficiency, it has been shown that massive MIMO systems employing dual-polarization can outperform the single-polarized counterpart with the same number of antenna elements [9], [12], [13]. With these benefits, multi-polarization in massive MIMO has become the standard choice for LTE-A deployments, and it is expected to be part of 5G and beyond [14]- [16].…”

This paper aims to design and evaluate the performance of multi-cluster multi-user dual-polarized massive multiple-input multiple-output (MIMO) systems with non-orthogonal multiple access (NOMA).Assuming the downlink mode in which a single base station communicates with multiple users, with all terminals being equipped with multiple co-located dual-polarized antennas, two precoder designs are proposed: (i) the first one aims to maximize the number of user groups that are simultaneously served within a cluster; and (ii) the second approach aims to provide further improvements compared to the first one by exploring polarization diversity. Closed-form expressions for the outage probability are derived for both approaches, based on which the respective asymptotic studies are carried out and the diversity gains are determined. The ergodic sum-rates are also derived. Representative numerical examples are presented along with insightful discussions. For instance, our results show that the proposed dual-polarized MIMO-NOMA designs outperform conventional single-polarized systems, even for high cross-polar interference. Simulation results are plotted to corroborate the analytical framework and analysis.
