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.

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 ...

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 ...

Improving Secrecy for Correlated Main and Wiretap Channels Using Cooperative Jamming

IEEE Access, 2019
To reduce the secrecy loss due to the correlation between main and wiretap channels, this paper introduces a cooperative jamming relay to degrade the reception at the eavesdropper.
