Artificial neural net based noise cancellor [PDF]
ACE '90. Proceedings of [XVI Annual Convention and Exhibition of the IEEE In India], 2005 This paper presents a new method for noise cancellation with an Artificial Neural Network. The network used is a feedforward one with three layers. The backpropagation and Stastical Cauchy's learning algorithms are employed for adaptation of the internal parameters of the network.

Artificial Noise Injection and Its Power Loading Methods for Secure Space-Time Line Coded Systems
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 ...

Secure MISO-NOMA Transmission With Artificial Noise [PDF]
IEEE Transactions on Vehicular Technology, 2018 This correspondence studies a new secrecy beamforming (SBF) scheme for multiple-input single-output non-orthogonal multiple access (MISO-NOMA) systems. In particular, the proposed SBF scheme efficiently exploits artificial noise to protect the confidential information of two NOMA assisted legitimate users, such that only the eavesdropper's channel is ...

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.

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 ...
