MIMO Secret Communications Against an Active Eavesdropper
Lingxiang Li, Athina P. Petropulu, Zhi Chen
This paper considers a scenario in which an Alice-Bob pair wishes to communicate in secret in the presence of an active Eve, who is capable of jamming as well as eavesdropping in F…
Transmit design for MIMO wiretap channel with a malicious jammer
Duo Zhang, Weidong Mei, Lingxiang Li +1
In this paper, we consider the transmit design for multi-input multi-output (MIMO) wiretap channel including a malicious jammer. We first transform the system model into the tradit…
GSVD-Based Precoding in MIMO Systems With Integrated Services
