Channel-Correlation-Enabled Transmit Optimization for MISO Wiretap Channels
Shuai Han, Sai Xu, Weixiao Meng +1
An artificial-noise (AN)-aided beamformer specific to correlated main and wiretap channels is designed in this paper. We consider slow-fading multiple-input-single-output (MISO) wi…
Artificial Noisy MIMO Systems under Correlated Scattering Rayleigh Fading -- A Physical Layer Security Approach
Yiliang Liu, Hsiao-Hwa Chen, Liangmin Wang +1
The existing investigations on artificial noise (AN) security systems assumed that only null spaces is used to send AN signals, and all eigen-subchannels should be used to transmit…
Physical Layer Security Enhancement for Satellite Communication among Similar Channels: Relay Selection and Power Allocation
Shuai Han, Xiangxue Tai, Weixiao Meng +1
Channels of satellite communication are usually modeled as Rician fading channels with very large Rician factor or Gaussian channels. Therefore, when a legitimate user is close to…
Resource Allocation Based on Deep Neural Networks for Cognitive Radio Networks
Fuhui Zhou, Xiongjian Zhang, Rose Qingyang Hu +2
Resource allocation is of great importance in the next generation wireless communication systems, especially for cognitive radio networks (CRNs). Many resource allocation strategie…
Improving Secrecy with Nearly Collinear Main and Wiretap Channels via a Cooperative Jamming Relay
Shuai Han, Sai Xu, Weixiao Meng +1
In physical layer security (PHY-security), the frequently observed high correlation between the main and wiretap channels can cause a significant loss of secrecy. This paper invest…
