Movable Frequency Diverse Array for Wireless Communication Security
Zihao Cheng, Jiangbo Si, Zan Li +3
Frequency diverse array (FDA) is a promising antenna technology to achieve physical layer security by varying the frequency of each antenna at the transmitter. However, when the ch…
Movable Frequency Diverse Array-Assisted Covert Communication With Multiple Wardens
Zihao Cheng, Jiangbo Si, Zan Li +3
The frequency diverse array (FDA) is highly promising for improving covert communication performance by adjusting the frequency of each antenna at the transmitter. However, when fa…
Cooperative Jamming for Secure Transmission With Both Active and Passive Eavesdroppers
Jiangbo Si, Zihao Cheng, Zan Li +3
Secrecy transmission is investigated for a cooperative jamming scheme, where a multi-antenna jam-mer generates artificial noise (AN) to confuse eavesdroppers. Two kinds of eavesdro…
Covert Surveillance via Proactive Eavesdropping Under Channel Uncertainty
Zihao Cheng, Jiangbo Si, Zan Li +2
Surveillance performance is studied for a wireless eavesdropping system, where a full-duplex legitimate monitor eavesdrops a suspicious link efficiently with the artificial noise (…
