Artificial Noise Aided Secure Transmission for Active RIS-Aided NOMA Networks
IEEE Access, 2023 A secrecy rate maximization problem for active reconfigurable intelligent surface (RIS) aided non-orthogonal multiple access networks has been studied in this paper. Assuming that the perfect channel state information is available, we aim to maximize the

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 ...

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.
