“…Hybrid beamforming strategies for dual-polarized millimeterwave MIMO systems were proposed in [27] and [28]. The work in [29] investigated the performance of a massive MIMO system with distributed polarized antennas, and dualpolarized MIMO systems assisted by intelligent reflecting surfaces (IRSs) were considered in [5], [6], and [30].…”

“…Furthermore, even though dual-polarized MIMO systems with different MA techniques have been investigated in recent works, this paper is the first in the literature to propose a dual-polarized MIMO-RSMA network and study ways to mitigate interference issues of SIC via the polarization domain. Only [5] and [6] have harnessed the features of wave polarization to alleviate SIC issues. However, these works studied dual-polarized MIMO-NOMA schemes assisted by IRSs, which are system models fundamentally different from the one proposed in this paper.…”

“…In addition to the space efficiency, the polarization domain offers a new degree of freedom (DoF) to MIMO systems, which can be exploited for generating both multiplexing and diversity gains. These advantages bring to dual-polarized MIMO systems performance improvements that can remarkably outperform single-polarized counterparts [1], [2], [5], [6].…”

The polarization domain provides an extra degree of freedom (DoF) for improving the performance of multiple-input multiple-output (MIMO) systems. This paper takes advantage of this additional DoF to alleviate practical issues of successive interference cancellation (SIC) in rate-splitting multiple access (RSMA) schemes. Specifically, we propose three dual-polarized downlink transmission approaches for a massive MIMO-RSMA network under the effects of polarization interference and residual errors of imperfect SIC. The first approach implements polarization multiplexing for transmitting the users' data messages, which removes the need to execute SIC in the reception. The second approach transmits replicas of users' messages in the two polarizations, which enables users to exploit diversity through the polarization domain. The third approach, in its turn, employs the original SIC-based RSMA technique per polarization, and this allows the BS to transmit two independent superimposed data streams simultaneously. An in-depth theoretical analysis is carried out, in which we derive tight closed-form approximations for the outage probabilities of the three proposed approaches. Accurate approximations for the ergodic sum-rates of the two first schemes are also derived. Simulation results validate the theoretical analysis and confirm the effectiveness of the proposed schemes. For instance, under low to moderate cross-polar interference, the results show that, even under high levels of residual SIC error, our dual-polarized MIMO-RSMA strategies outperform the conventional single-polarized MIMO-RSMA counterpart. It is also shown that the performance of all RSMA schemes is impressively higher than that of single and dual-polarized massive MIMO systems employing nonorthogonal multiple access (NOMA) and orthogonal multiple access (OMA) techniques.

“…Thus, the conventional independent and identically distributed assumption cannot be directly adopted to model co-/cross-polarized channels [21]. However, in most of the existing literature, the power of co-polarized channels is assumed to be equal [22], [23], [26], which is not efficient. Therefore, a realistic channel model including polarization is required.…”

This paper investigates the utilization of triple polarization (TP) for multi-user (MU) holographic multiple-input multi-output surface (HMIMOS) wireless communication systems, targeting at capacity boosting and diversity exploitation without enlarging the antenna array sizes. We specifically consider that both the transmitter and receiver are both equipped with an HMIMOS consisting of compact sub-wavelength TP patch antennas within near-field (NF) regime. To characterize TP MU-HMIMOS L. Wei and C. Yuen are with the Engineering Product Development (EPD) Pillar,
