IET Communications, Volume 17, Issue 2, Page 171-182, January 2023., 2023 Abstract In this article, robust beamforming (BF) and artificial noise (AN) design method is proposed for multiuser broadcast secure transmission under secrecy outage probability (SOP) constraints. A special scenario is assumed that the transmitter cannot obtain the accurate channel state information (CSI) of the users' channel, and different users ...

Analysis of Eavesdropping Region in Hybrid mmWave‐Microwave Wireless Systems
Wireless Communications and Mobile Computing, Volume 2023, Issue 1, 2023., 2023 Hybrid communication systems, where millimeter‐wave (mmWave) links coexist with microwave links, have been an essential component in the fifth‐generation (5G) wireless networks. Nevertheless, the open feature of the wireless medium makes hybrid systems vulnerable to eavesdropping attacks.
