“…Next, we firstly design a suboptimal solution to handle the non-convex power optimization problem in (8) with the appropriate relaxation and the SCA algorithm [18]. After converting the optimization problem in (8) to two strictly convex optimization problems, we further present a joint iterative power optimization algorithm for both the cellular user and D2D transmitter node.…”

“…To overcome this issue, physical-layer security (PLS) [4][5][6][7][8][9] has been recently proposed to employ the opening characters of wireless channels to achieve secret communication, resulting in achieving "absolute" security from the concept of information theory. There has been some work to exploit PLS for D2D communications.…”

In this paper, a secure transmission scheme based on the artificial noise is proposed for D2D communications underlaying the full-duplex cellular network, and a secure power allocation scheme to maximize the overall secrecy rate of both the cellular user and D2D transmitter node is presented. Firstly, the full-duplex base station transmits the artificial noise to guarantee the secure communications when it receives signals of cellular uplinks. Under this secure framework, it is found that improving the transmission power of the cellular user or the D2D transmitter node will degrade the secrecy rate of the other, although will improve itself secrecy rate obviously. Hence, a secure power allocation scheme to maximize the overall secrecy rate is presented subject to the security requirement of the cellular user. However, the original power optimization problem is non-convex. To efficiently solve it, we recast the original problem into a convex program problem by utilizing the proper relaxation and the successive convex approximation algorithm. Simulation results evaluate the effectiveness of the proposed scheme. . He then received the M.S. degree in NDSC. He has been a faculty member of NDSC since 2014.

“…As another important metric, the widely discussed secrecy throughput presented the average reliable and secure rate during each transmission [8][9][10]. Moreover, signal-processing methods, e.g., beamforming and artificial noise, efficiently enhanced the secrecy performance [11][12][13][14][15][16][17][18]. It was also proposed that diversity technologies had their special functions in PLS, including multi-input multi-output (MIMO) diversity and multi-user diversity [19].…”

In a hybrid automatic repeat request with chase combining (HARQ-CC) system, we analyze physical layer secure performance and determine the secrecy redundancy rate by proposed quasi-concave optimization methods with effective secrecy throughput (EST) criteria. First, key performance metrics, including connection outage probability (COP), secrecy outage probability (SOP), EST, and delay, are discussed. Then, under the constraint of COP, we optimize the secrecy redundancy rate to maximize the EST, which is a quasi-concave function, by both the bisection and fixed-point methods. Furthermore, under the simultaneous constraints of COP and SOP, the bisection and Lagrangian multiplier methods are applied to optimize the secrecy redundancy rate. From the comparison of the numerical and simulated results, it is concluded that EST demonstrates practical secure performance of HARQ-CC, and the proposed optimization methods adjust the secrecy redundancy rate for improved security.

“…wireless spectrum resources are becoming increasingly scarce. To meet the growing communication demands of customers, the spectral efficiency of the existing wireless networks must be substantially improved [1]- [5]. Meanwhile, the base stations (BSs) under the conventional BS-centric cellular network architecture may often operate at an overloaded status (especially in a rush hour), thus resulting in a severe load imbalance over the network [6].…”

Both Device-to-device (D2D) and full-duplex (FD) have been widely recognized as spectral efficient techniques in the fifth-generation wireless communications systems. By enabling FD mode in D2D communications, the attainable spectrum efficiency can be (in theory) up to twice as high as that of conventional half-duplex (HD) mode D2D technology, provided that the selfinterference signal in the former can be sufficiently suppressed. Considering the fact that FD technology does not always outperform the HD technology in arbitrary channel condition, we will delve into the FD gain as well as its preconditions for acquisition in this paper. In particular, the performance of D2D-aided underlaying cellular networks is investigated by assuming that the D2D users are capable of operating at both HD and FD modes. Under a given user workload, the sum throughput in each DU is shown to be always improved by activating D2D links despite an extra DU-induced interference could be imposed on its cospectrum cellular users. Numerical results show that the FD-D2D mode exhibits its superiority in terms of sum throughput than the HD-D2D mode in a light-workload scenario even if a non-ideal SI cancellation has been implemented in the former, but the latter pulls back a game in a heavy-workload scenario. Furthermore, to maximize the sum throughput, an appropriate mode-selection scheme (i.e., by choosing either FD or HD mode in the current time-slot for each individual D2D user) should be implemented for sufficiently exploiting the FD gain according to the instantaneous radio frequency environment.
