“…With perfect CSI available, we compare our proposed scheme with three benchmarks, including the zero-forcing reception and zero-forcing transmission scheme proposed in [60] (denoted as "ZFR-ZFT") and the maximal-ratio reception and maximal-ratio transmission scheme proposed in [61] (denoted as "MRR-MRT") and our proposed scheme with randomly generated AN (denoted as "RandAN"). If not specified, we set the transmit power budget of the sensors, relay and AP is P s /σ 2 = 10 dB, P r /σ 2 = 30 dB and P ap /σ 2 = 40 dB, the minimum MSE constraint at the relay is ξ r = 3, and the SINR threshold at the sensors is ρ = 2 dB.…”

In this paper, we investigate joint optimization of secure AirComp and reliable multicasting assisted by a multipleinput multiple-output untrusted two-way relay, where artificial noise is employed at the access point (AP) to interfere the relay for ensuring secure AirComp. We aim to minimize the computation distortion at the AP by jointly designing the transmit variables of all the nodes and the aggregation variables at the AP and relay, under the secure AirComp constraint, the reliable multicasting constraint, and the transmit power constraints of all the nodes. We consider two scenarios that perfect and imperfect channel state information (CSI) are available. For the former, the formulated optimization problem is highly nonconvex, and we propose an effective block coordinate descent (BCD)penalty successive convex approximation (penaltySCA) method to solve the nonconvex problem. For the latter, we model the imperfect CSI by using worst-case criterion and the formulated robust optimization problem is much more challenging than its counterpart with perfect CSI. To solve the robust problem effectively, we first transform it to a deterministic optimization problem by employing some powerful mathematical lemmas, and then apply the proposed BCD-penaltySCA method to solve the reformulated deterministic problem. The proposed methods are shown by simulations to significantly reduce the computation distortion compared with other benchmarks under considering secure AirComp and reliable multicasting.

“…With the objective of maximizing the secrecy rate and SEE, the PSand TS-based SWIPT relaying strategies have been examined for single-antenna user and relay nodes under Rayleigh fading channel conditions. In [195], an AF-based two-way MIMO relay-assisted CR NOMA network that employs the SWIPT technology in order to enhance network energy efficiency has been analyzed. In this study, the authors have focused on a scenario in which a pair of primary users and two pairs of secondary users (SUs) exchange information with the help of a MIMO two-way relay.…”

Increasing number of devices connected to the networks, applications and demands of new generation wireless communications cause very high energy consumption resulting in large amount of carbon emission. Thus, energy harvesting solutions together with accomplishing information transmission are required for energy efficient communications of new wireless communications generations such as 5G and 6G (i.e., 5G+). As such, due to the promise of energy efficient green communications, simultaneous wireless information and power transfer (SWIPT) techniques are expected to be indispensable component of 5G+. In this survey, the literature of multiuser SWIPT communications is reviewed for 5G+. Different multiuser SWIPT scenarios including multi-antenna communications, cooperative communications, network coding, communications security, and unmanned aerial vehicle (UAV)-enabled communication systems based on multiuser diversity and multiple access methods are thoroughly reviewed. The experimental studies are also discussed.

“…Similarly, cooperative communications have sparked substantial attention in research and industry because of their superior performance characteristics such as system capacity and transmission range, including the simplicity with which they may be implemented [ 15 , 16 , 17 , 18 ]. The fundamental notion is driven by the fact that, in a wireless context, the signal sent by a source to a destination is also heard by other endpoints, which are frequently known as relays.…”

Modulation awareness and cooperative transmissions have individually received a significant amount of research in the scholarly literature. However, a limited number of works are principally concerned with the combination of the two topics, and they are restricted to frequency-flat wireless channels. In this study, we propose a new modulation awareness method applicable to dual-hop amplify-and-forward cooperative broadcasts. The suggested method is built on the creation of theoretical representations of cross-correlation functions of the received signals. We conceptually prove that a family of modulation types generates spikes for certain cross-correlation functions, while others do not. We create a numerous layer hypothesis evaluation for the purpose of making judgments centered on this attribute. The suggested method has a number of benefits, such as the ability to operate on both frequency-flat and frequency-selective channels, as well as the absence of the necessity of channel awareness or noise power. Computer simulations analyze the performance of the proposed method, which delivers adequate awareness performance in a variety of operational scenarios.
