Robust transmission design for artificial noise aided multiuser broadcast system in inaccurate channel state information scenario with users of different importance

open access: yesIET 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 ...
