Secure Wireless Communications via Cooperation
Lun Dong, Zhu Han, Athina P. Petropulu +1
The feasibility of physical-layer-based security approaches for wireless communications in the presence of one or more eavesdroppers is hampered by channel conditions. In this pape…
Performance Analysis of a Cross-layer Collaborative Beamforming Approach in the Presence of Channel and Phase Errors
Lun Dong, Athina P. Petropulu, H. Vincent Poor
Collaborative beamforming enables nodes in a wireless network to transmit a common message over long distances in an energy efficient fashion. However, the process of making availa…
A High-Throughput Cross-Layer Scheme for Distributed Wireless Ad Hoc Networks
Athina P. Petropulu, Lun Dong, H. Vincent Poor
In wireless ad hoc networks, distributed nodes can collaboratively form an antenna array for long-distance communications to achieve high energy efficiency. In recent work, Ochiai,…
Blind Identification of Distributed Antenna Systems with Multiple Carrier Frequency Offsets
Yuanning Yu, Athina P. Petropulu, H. Vincent Poor
In spatially distributed multiuser antenna systems, the received signal contains multiple carrier-frequency offsets (CFOs) arising from mismatch between the oscillators of transmit…
