Optimal Beamforming for Physical Layer Security in MISO Wireless Networks
Zhichao Sheng, Hoang Duong Tuan, Trung Q. Duong +1
A wireless network of multiple transmitter-user pairs overheard by an eavesdropper, where the transmitters are equipped with multiple antennas while the users and eavesdropper are…
Low-Latency Multiuser Two-Way Wireless Relaying for Spectral and Energy Efficiencies
Zhichao Sheng, Hoang Duong Tuan, Trung Q. Duong +2
The paper considers two possible approaches, which enable multiple pairs of users to exchange information via multiple multi-antenna relays within one time-slot to save the communi…
Power Allocation for Energy Efficiency and Secrecy of Interference Wireless Networks
Zhichao Sheng, Hoang Duong Tuan, Ali Arshad Nasir +2
Considering a multi-user interference network with an eavesdropper, this paper aims at the power allocation to optimize the worst secrecy throughput among the network links or the…
Joint Power Allocation and Beamforming for Energy-Efficient Two-Way Multi-Relay Communications
Zhichao Sheng, Hoang D. Tuan, Trung Q. Duong +1
This paper considers the joint design of user power allocation and relay beamforming in relaying communications, in which multiple pairs of single-antenna users exchange informatio…
