Artificial-noise-aided Secure Multicast Precoding for Directional Modulation Systems
Feng Shu, Ling Xu, Jiangzhou Wang +2
In multi-cast scenario, all desired users are divided into groups. Each group receives its own individual confidential message stream. Eavesdropper group aims to intercept …
Low-Complexity and High-Resolution DOA Estimation for Hybrid Analog and Digital Massive MIMO Receive Array
Feng Shu, Yaolu Qin, Tingting Liu +4
A large-scale fully-digital receive antenna array can provide very high-resolution direction of arrival (DOA) estimation, but resulting in a significantly high RF-chain circuit cos…
Covert Communications with A Full-Duplex Receiver over Wireless Fading Channels
Jinsong Hu, Khurram Shahzad, Shihao Yan +3
In this work, we propose a covert communication scheme where the transmitter attempts to hide its transmission to a full-duplex receiver, from a warden that is to detect this cover…
GPI-based Secrecy Rate Maximization Beamforming Scheme for Wireless Transmission with AN-aided Directional Modulation
Hai Yu, Simin Wan, Wenlong Cai +7
In a directional modulation network, a general power iterative (GPI) based beamforming scheme is proposed to maximize the secrecy rate (SR), where there are two optimization variab…
Pilot Optimization and Power Allocation for OFDM-based Full-duplex Relay Networks with IQ-imbalances
Jin Wang, Hai Yu, Yongpeng Wu +4
In OFDM relay networks with IQ imbalances and full-duplex relay station (RS), how to optimize pilot pattern and power allocation using the criterion of minimizing the sum of mean s…
Covert Communication Achieved by A Greedy Relay in Wireless Networks
