Robust Beamforming Design for Secure DM-Based Relay Networks With Self-Sustained Jammers
IEEE Access, 2019 In this paper, we propose to use self-sustained jammers to generate artificial noise with the aim of enhancing the physical layer security of a directional modulation (DM) relay system.

Artificial-Noise-Aided CQI-Mapped Generalized Spatial Modulation
IEEE Transactions on Vehicular Technology, 2023 The artificial noise (AN) aided channel quality indicator (CQI) mapped generalized spatial modulation (GSM) philosophy is proposed for improving the security of legitimate links. Given the randomness of the legitimate CQI, eavesdroppers cannot successfully decode the confidential information. We analyse both the secrecy rate as well as the eavesdropper’

Cooperative Beamforming With Artificial Noise Injection for Physical-Layer Security
IEEE Access, 2023 In the sixth-generation (6G) communications, how to deploy and manage massively connected Internet-of-Things (IoT) nodes will be one of the key technical challenges, because 6G is expected to provide 10 times higher connection, compared to 5G.

Directional Modulation-Enhanced Multiple Antenna Arrays for Secure and Precise Wireless Transmission
Sensors, 2019 Directional modulation (DM) technique has the ability to enhance the physical layer security (PLS) of wireless communications. Conventional DM schemes are usually based on a single antenna array with the basic assumption that eavesdroppers (Eves) and ...

Covert Wireless Communication With Artificial Noise Generation
IEEE Transactions on Wireless Communications, 2018 Covert communication conceals the transmission of the message from an attentive adversary. Recent work on the limits of covert communication in additive white Gaussian noise (AWGN) channels has demonstrated that a covert transmitter (Alice) can reliably transmit a maximum of $\mathcal{O}\left(\sqrt{n}\right)$ bits to a covert receiver (Bob) without ...

Noise-adaptive Margin-based Active Learning and Lower Bounds under Tsybakov Noise Condition [PDF]
, 2015 We present a simple noise-robust margin-based active learning algorithm to find homogeneous (passing the origin) linear separators and analyze its error convergence when labels are corrupted by noise.

Propagation of numerical noise in particle-in-cell tracking
, 2015 Particle-in-cell (PIC) is the most used algorithm to perform self-consistent tracking of intense charged particle beams. It is based on depositing macro-particles on a grid, and subsequently solving on it the Poisson equation.

Cooperative Secret Communication with Artificial Noise in Symmetric Interference Channel
, 2010 We consider the symmetric Gaussian interference channel where two users try to enhance their secrecy rates in a cooperative manner. Artificial noise is introduced along with useful information.
