This paper considers transmit optimization in multi-input multi-output (MIMO) wiretap
channels, wherein we aim at maximizing the secrecy capacity or rate of an MIMO channel …

In this paper, we consider a buffer-aided multiuser multiple-input single-output (MISO)
network consisting of one multi-antenna access point (AP) and multiple single-antenna …

In this letter, we address physical layer security in MISO communications in the presence of
passive eavesdroppers, ie, the eavesdroppers' channels are unknown to the transmitter …

A Gaussian MISO (multiple input single output) channel is considered where a transmitter is
communicating to a receiver in the presence of an eavesdropper. The transmitter is …

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 …

We consider a Gaussian multiple-input multiple-output (MIMO) wiretap channel model,
where there exists a transmitter, a legitimate receiver and an eavesdropper, each node …

This paper considers a unicast multiuser multiple-input single-output (MISO) downlink
system overheard by multiple single-antenna eavesdroppers. The objective is to jointly …

Multi-user Gaussian MIMO wiretap channel is considered under interference power
constraints (IPC), in addition to the total transmit power constraint (TPC). Algorithms for …

In wireless communication, the transmitter (Alice) can send artificial noise (AN) to interfere
with the eavesdropper (Eve). This letter considers the AN MIMO scenario, ie, both Alice and …

In this paper, we consider the problem of optimizing the transmit co-variance matrix for a
multiple-input multiple-output (MIMO) Gaussian wiretap channel. The scenario of interest …
