On Cooperative Beamforming Based on Second-Order Statistics of Channel State Information
Jiangyuan Li, Athina P. Petropulu, H. Vincent Poor
Cooperative beamforming in relay networks is considered, in which a source transmits to its destination with the help of a set of cooperating nodes. The source first transmits loca…
On Ergodic Secrecy Capacity for Gaussian MISO Wiretap Channels
Jiangyuan Li, Athina P. Petropulu
A Gaussian multiple-input single-output (MISO) wiretap channel model is considered, where there exists a transmitter equipped with multiple antennas, a legitimate receiver and an e…
Optimal Cooperative Relaying Schemes for Improving Wireless Physical Layer Security
Jiangyuan Li, Athina P. Petropulu, Steven Weber
We consider a cooperative wireless network in the presence of one of more eavesdroppers, and exploit node cooperation for achieving physical (PHY) layer based security. Two differe…
