Artificial noise-aided biobjective transmitter optimization for service integration in multi-user MIMO broadcast channel

Abstract: This paper considers an artificial noise (AN)-aided transmit design for multi-user MIMO systems with integrated services. Specifically, two sorts of service messages are combined and served simultaneously: one multicast message intended for all receivers and one confidential message intended for only one receiver and required to be perfectly secure from other unauthorized receivers. Our interest lies in the joint design of input covariances of the multicast message, confidential message, and artificial noise (… Show more

“…In [22], an AN-aided transmission was designed to enhance the secrecy rate region with both confidential and multicast services in a multi-user MISO broadcast channel. This work was extended to a multi-user MIMO scenario in [23]. For a cognitive satellite-terrestrial network, the authors in [24] explored the advantage of AN to provide the additional degree-of-freedom (DoF) against the overhearing from the primary network.…”
