Artificial Noise in Adaptive Arrays

IEEE Transactions on Aerospace and Electronic Systems, 1978
"Artificial noise," or the connection of feedback paths around the the integrators, is shown to be an effective method of dealing with the problem of multiplier offsets in adaptive antennas. This probl which was analyzed by Compton [1] is particularly troubles when the covariance matrix is singular or nearly so.

Deep Artificial Noise: Deep Learning-Based Precoding Optimization for Artificial Noise Scheme

IEEE Transactions on Vehicular Technology, 2020
In this work, we consider a secure precoding optimization problem for the artificial noise (AN) scheme in multiple-input single-output (MISO) wiretap channels. In previous researches (Lin et al. , 2013), it was proved that the generalized AN scheme which allows some portion of AN signal to be injected to the legitimate receiver's channel is the ...

Profiling of Urban Noise Using Artificial Intelligence

Computer Systems Science and Engineering, 2023
La contaminación acústica tiende a recibir menos conciencia en comparación con otros tipos de contaminación, sin embargo, afecta en gran medida la calidad de vida de los seres humanos, como causar trastornos del sueño, estrés o discapacidad auditiva. El perfil del sonido urbano a través de la identificación de fuentes de ruido en las ciudades podría ...

Guaranteeing Secrecy using Artificial Noise

IEEE Transactions on Wireless Communications, 2008
The broadcast nature of the wireless medium makes the communication over this medium vulnerable to eavesdropping. This paper considers the problem of secret communication between two nodes, over a fading wireless medium, in the presence of a passive eavesdropper.
