“…Meanwhile, we should inform that = 0 technically means the perfect CSI case. Figure 4 shows the observably more efficient secrecy capacity for our approach compared to the worst-case method prevalently utilised in the literature [39][40][41], while changing and and also having = 50mWatt. Such strong reinforcement is effectively justified by the markedly more adequate convergence for P 4 , analytically caused by convexity comprehensively originated from solvability.…”

The paper principally proposes a suboptimally closed-form solution in terms of a general asymptotic bound of the secrecy capacity in relation to MIMOME-based transceivers. Such pivotal solution is essentially tight as well, fundamentally originating from the principle convexity. The resultant novelty, per se, is strictly necessary since the absolutely central criterion imperfect knowledge of the wiretap channel at the transmitter should also be highly regarded. Meanwhile, ellipsoidal channel uncertainty set-driven strategies are physically taken into consideration. Our proposed solution is capable of perfectly being applied for other general equilibria such as multiuser ones. In fact, this in principle addresses an entirely appropriate alternative for worst-case method-driven algorithms utilising some provable inequality-based mathematical expressions. Our framework is adequately guaranteed regarding a totally acceptable outage probability (as 1 − preciseness coefficient). The relative value is almost 10% for the estimation error values (EEVs) ⩽ 0.5 for 2 × 2-based transceivers, which is noticeably reinforced at nearly 5% for EEVs ⩽ 0.9 for the case 4 × 4. Furthermore, our proposed scheme basically guarantees the secrecy outage probability (SOP) less than 0.05% for the case of having EEVs ⩽ 0.3, for the higher power regime.

“…• Multi-antenna broadcast networks: In such settings, simultaneous wireless information and power transfer is implemented by transmission beamforming which is designed to jointly or separately satisfy the constraints of secrecy rate, secrecy outage probability, energy-harvesting outage probability, and received SINR ratio [229]- [235]. In order to achieve secure transmission, the transmission beamforming is also aided with AN strategy in many works [230]- [235]. • Distributed antenna systems: In [236], the beamforming and AN vectors are jointly optimized to minimize the total transmission power while providing QoS for reliable communication and efficient power transfer in a given time slot, in which the capacity-limited backhaul links is taken into account.…”

Due to the malicious attacks in wireless networks, physical layer security has attracted increasing concerns from both academia and industry. The research on physical layer security mainly focuses either on the secrecy capacity/achievable secrecy rate/capacity-equivocation region from the perspective of information theory, or on the security designs from the viewpoints of optimization and signal processing. Because of its importance in security designs, the latter research direction is surveyed in a comprehensive way in this paper. The survey begins with typical wiretap channel models to cover common scenarios and systems. The topics on physical-layer security designs are then summarized from resource allocation, beamforming/precoding, and antenna/node selection and cooperation. Based on the aforementioned schemes, the performance metrics and fundamental optimization problems are discussed, which are generally adopted in security designs. Thereafter, the state of the art of optimization approaches on each research topic of physical layer security is reviewed from four categories of optimization problems, such as secrecy rate maximization, secrecy outrage probability minimization, power consumption minimization, and secure energy efficiency maximization. Furthermore, the impacts of channel state information on optimization and design are discussed. Finally, the survey concludes with the observations on potential future directions and open challenges.

“…As conventional battery is not convenient for such a huge number of devices, simultaneous wireless information and power transfer (SWIPT) is recognized as a promising technology to prolong the operation time of wireless devices [3]- [14]. The separated information receiver (IR) and energy receiver (ER) are considered in [3]- [5]. The authors in [3], [15] considered a multi-user wireless information and power transfer system, where the beamforming vector was designed by the zero-forcing (ZF) algorithm and updated by maximizing the energy harvested.…”

“…In [4], the optimal beamforming scheme was proposed for achieving the maximum secrecy rate, while meeting the minimum energy requirement at the ER. In [5], [16], the authors designed the robust information and energy beamforming vectors for maximizing the energy harvested by Xiaobo the ER under specific constraints on the signal-to-interference plus noise ratio (SINR) at the IR. A power splitting (PS) scheme was utilized to divide the received signal into two parts in order to simultaneously harvest energy and to decode information [6], [7], [9], [10].…”

Secure wireless information and power transfer based on directional modulation is conceived for amplify-andforward (AF) relaying networks. Explicitly, we first formulate a secrecy rate maximization (SRM) problem, which can be decomposed into a twin-level optimization problem and solved by a one-dimensional (1D) search and semidefinite relaxation (SDR) technique. Then in order to reduce the search complexity, we formulate an optimization problem based on maximizing the signal-to-leakage-AN-noise-ratio (Max-SLANR) criterion, and transform it into a SDR problem. Additionally, the relaxation is proved to be tight according to the classic Karush-Kuhn-Tucker (KKT) conditions. Finally, to reduce the computational complexity, a successive convex approximation (SCA) scheme is proposed to find a near-optimal solution. The complexity of the SCA scheme is much lower than that of the SRM and the Max-SLANR schemes. Simulation results demonstrate that the performance of the SCA scheme is very close to that of the SRM scheme in terms of its secrecy rate and bit error rate (BER), but much better than that of the zero forcing (ZF) scheme.Index Terms-Directional modulation, simultaneous wireless information and power transfer, AF, artificial noise, secrecy rate.
