The Secrecy Capacity Optimization Artificial Noise: A New Type of Artificial Noise for Secure Communication in MIMO System [PDF]
IEEE Access, 2019 In multiple-input multiple-output wireless communication system, artificial noise (AN) is designed to be aligned into the null space of the legitimate channel so that it has no effect on the legitimate channel.

Induced internal noise in perceptual artificial scotomas created by surrounding dynamic noise
Vision Research, 2007 Research has shown that exposure to a homogeneous gray patch surrounded by a dynamic noise background causes filling-in of the artificial scotoma by the twinkling noise from the surround. When the background is switched off, observers report perception of a prolonged patch of twinkling noise in the unstimulated area.

Artificial Noise Injection and Its Power Loading Methods for Secure Space-Time Line Coded Systems [PDF]
Entropy, 2019 In this paper, we consider a 2 × 2 space-time line coded (STLC) system having two-transmit and two-receive antennas. To improve the secrecy rate of the STLC system, in which an illegitimate receiver eavesdrops the information delivered from ...

Practical Secrecy using Artificial Noise [PDF]
IEEE Communications Letters, 2013 In this paper, we consider the use of artificial noise for secure communications. We propose the notion of practical secrecy as a new design criterion based on the behavior of the eavesdropper's error probability $P_E$, as the signal-to-noise ratio goes to infinity.

Antenna Grouping-Based Blind Artificial Noise for TDD Secure Transmission
IEEE Access, 2021 The artificial noise (AN-) aided techniques have been considered as promising candidates to enhance the physical layer security. However, the effect of AN on an eavesdropper (Eve) can be severely degraded as the number of antennas at Eve increases.

Impact of Channel Estimation-and-Artificial Noise Cancellation Imperfection on Artificial Noise-Aided Energy Harvesting Overlay Networks [PDF]
Telecommunication Systems, 2021 Abstract EHONs (Energy Harvesting Overlay Networks) satisfy stringent design requirements such as high energy-and-spectrum utilization efficiencies. However, due to open access nature of these networks, eavesdroppers can emulate cognitive radios to wire-tap legitimate information, inducing information security to become a great concern.

Artificial Noise Revisited [PDF]
IEEE Transactions on Information Theory, 2015 The artificial noise (AN) scheme, proposed by Goel and Negi, is being considered as one of the key enabling technology for secure communications over multiple-input multiple-output (MIMO) wiretap channels. However, the decrease in secrecy rate due to the increase in the number of Eve's antennas is not well understood.
