This letter considers a two-receiver multiple-input single-output Gaussian broadcast channel
model with integrated services. Specifically, two sorts of service messages are combined …

In recent years there has been growing interest in study of multi-antenna transmit designs for
providing secure communication over the physical layer. This paper considers the scenario …

We consider two-user MIMO broadcast and interference channels in which confidential
messages intended for each receiver are kept secret from the other receiver. The …

The notion of providing secure communication via physical-layer designs has gained much
attention in recent studies. This paper considers the transmit covariance design for a …

This paper studies the secrecy capacity of the multiple input single output (MISO) secrecy
channel where a transmitter is communicating to a receiver in the presence of K …

Recently, there has been growing interest in secure communication via multi-antenna
physical-layer designs. In this paper, we consider a transmit covariance design for a secrecy …

This paper considers artificial noise (AN) aided transmit designs for multiuser MISO systems
in the eyes of service integration. Specifically, we combine two sorts of services, and serve …

The advances of multi-antenna techniques has recently led to renewed interest in physical-
layer secrecy, a meaningful topic that enables us to prevent eavesdroppers from retrieving …

Consider a scenario in which an MISO channel is overheard by multiple single-antenna
eavesdroppers. The transmitter has perfect channel state information (CSI) with the …

Consider an MISO channel overheard by multiple eavesdroppers. Our goal is to design an
artificial noise (AN)-aided transmit strategy, such that the achievable secrecy rate is …
