This paper considers an artificial noise (AN)-aided transmit design for multi-user MISO systems in the eyes of service integration. Specifically, we combine two sorts of services, and serve them simultaneously: one multicast message intended for all receivers and one confidential message intended for only one authorized receiver. The confidential message is kept perfectly secure from all the unauthorized...
We consider the problem of physical layer service integration for the multiple-input single-output (MISO) Gaussian Broadcast Channel (BC). In particular, we study a scenario with two receivers and two messages: one common message intended for both receivers and one confidential message for only receiver 1 which needs to be kept perfectly secure from receiver 2. With partially known Channel state information...
