“…Although NOMA has been explored in variety contexts of wireless communication systems (e.g., cognitive radio [3], energy harvesting [4], visible light communication [5], reconfigurable intelligent surface [6], short-packet communication [7], etc. ), such technology introduces some challenges involving high complexity, imperfect SIC, and limited coverage, which may limit its performance and practicality [8].…”

This work proposes a novel scheme of non-orthogonal multiple access (NOMA) combined with cache-enabled maritime device-to-device communication (D2D) networks, which aims to improve the performance of ship users located far from the shore and also reduce the data traffic load at the coastal base station. Taking into account the quality-of-service demands of near ship users along with the poor channel condition of far ship users, a joint beamforming design and NOMA power allocation issue is also considered. In addition, three kinds of decoding order at far ship users are also studied to comprehensively characterize the superiority of the proposed systems. Accordingly, the performance of users is then quantified in terms of outage probability and ergodic capacity, where the respective exact expressions are also evaluated in closed form. Qualitative numerical results corroborates the developed theoretical analysis and reveals that:(1) The adoption of the proposed decoding order scheme to improve the outage performance of far ship users is strongly dominated by the trade-off power setting between the coastal base station and the near ship use; and (2) The ergodic rate achieved by the proposed NOMA with cache-aided maritime full-duplex D2D communication network always outperforms those of benchmark schemes, particularly in saving at least 2.5 dB of transmitting power budget for far ship users and achieving double ergodic capacity for near ship users.INDEX TERMS Device-to-device communications (D2D), marine vehicles, non-orthogonal multiple access (NOMA), ship-to-everythings (S2X), wireless caching.

“…However, it remains difficult to satisfy the demands of IoT applications in the future that will support hundreds of billions of linked devices [3,4]. Non-orthogonal multiple-access (NOMA) approaches are a wellstudied strategy for offering significant spectral efficiency (SE) use in IoT networks [5][6][7], satellite networks [8][9][10], and V2V networks [11,12]. NOMA enables several users to use the same time and frequency block with varying transmit power allocations [13,14].…”

In this paper, we investigate a novel power beacon (PB)-aided wireless sensor-powered non-orthogonal multiple-access (NOMA) Internet-of-Things (IoT) network under imperfect channel state information (CSI). Furthermore, the exact expression outage probability (OP) of two IoT users is derived to analyze the performance of the considered network. To give further insight, the expression asymptotic OP and diversity order are also expressed when the transmit power at the PB goes to infinity. Furthermore, a deep neural network (DNN) framework is proposed to concurrently forecast IoT users’ OP in relation to real-time setups for IoT users. Additionally, when compared to the traditional analysis, our created DNN shows the shortest run-time prediction, and the outcomes predicted by the DNN model almost match those of the simulation. In addition, numerical results validate our analysis, simulation, and prediction through a Monte Carlo Simulation. Furthermore, the results show the impact of the main parameter on our proposed system. Finally, these findings show that NOMA performs better than the conventional orthogonal multiple-access (OMA) techniques.

“…The millimeter wave (mmWave) spectrum is an essential element of fifth-generation (5G) and future (6G) wireless communications, as stated in [2]. The mmWave technology offers the benefit of increased capacity [3] and more focused beams [4,5], but it comes with the drawback of greater loss of signal when penetrating buildings. The aforementioned disadvantage is often reduced by employing relays to connect indoor users to outdoor transceivers, along with the implementation of scalable massive multiple-input-multipleoutput (mMIMO) configurations [6,7] to enhance signal coverage [8,9], utilizing nearly optimal linear processing techniques (such as zero-forcing (ZF) and maximum-ratio (MR)), and reducing channel estimation complexity (using achieved channel hardening, among other methods).…”

Assuming incomplete knowledge of the channel state information (CSI), we investigate two scenarios involving millimeter wave (mmWave) relaying to support outdoor-to-indoor communications. We proceed to derive the average signal-to-noise ratio (SNR) expressions for two relaying scenarios and quantify the asymptotic SNR. The performance of the two relaying scenarios is evaluated using the outage probability—for which we have derived closed-form equations—the end-to-end channel capacity, and the energy efficiency. The obtained results are compared with those derived assuming complete knowledge of the CSI. The effect of the imperfect CSI is therefore assessed in relation to the reference of perfect CSI. In these scenarios, an outside base station (BS) in an urban cellular network serves several indoor users. In the context of a two-hop full-duplex (FD) relaying scheme, we initially suggest a method in which the base station (BS) utilizes zero-forcing (ZF) precoding, and we take into account the overall channel response. Furthermore, we make the assumption that the base station (BS) engages in precoding only depending on the response of the channel in the first hop; in this second design, the relay precodes (using the response of the second-hop channel), amplifies, and sends the signals. Both techniques utilize massive multiple-input–multiple-output (mMIMO) arrays to permit transmission. We also present Monte Carlo simulation results to assess the accuracy of our analytical results. Finally, the two systems are compared in terms of channel estimation and precoding complexity, the number of antennas, as well as the number of users. Practical deployment recommendations are formulated at the end of this work.
