Due to the openness of wireless communication, information transmitted in the multiple
access channel is vulnerable to eavesdropping by illegitimate users. Classic artificial noise …

With non-orthogonal multiple access (NOMA) in a passive eavesdropping scenario, we
tackle the maximization of the secrecy rate for the strong user subject to a maximum …

We consider physical layer security in a multi-input multi-output multi-eavesdropper wiretap
channel and present an exact solution to the problem of secrecy rate maximization. A system …

Secure precoding superimposed with artificial noise (AN) is a promising transmission
technique to improve security by harnessing the superposition nature of the wireless …

Large-scale multiple input multiple output (MIMO) wireless system is regarded as a solution
to provide high speed connection for exponentially increasing wireless subscriptions for …

This paper studies the beamforming design problem of a multiuser downlink network,
assuming imperfect channel state information known to the base station. In this scenario, the …

This paper examines linear beamforming methods for secure communications in a multiuser
wiretap channel with a single transmitter, multiple legitimate receivers, and a single …

In this paper, we consider the problem of jointly designing transmit precoding (TPC) matrix
and receive filter matrix subject to both secrecy and per-transmitter power constraints in the …

Robust quality-of-service (QoS)-based and secrecy rate-based secure transmission designs
are investigated for a multiple-input single-output system with multiple eavesdroppers and a …

Integrated radar and communication (IRC) systems are promising in the next generation
wireless communication networks. However, to realize high level security of information …
