We consider the problem of secure communication with multiantenna transmission in fading
channels. The transmitter simultaneously transmits an information-bearing signal to the …

In this paper, we study the secure multiantenna transmission with artificial noise (AN) under
imperfect channel state information (CSI) in the presence of spatially randomly distributed …

We analyze and optimize the secrecy performance of artificial noise (AN) in multi-input
single-output wiretap channels with multiple antennas at the transmitter and a single …

In this paper, we study the secure multi-antenna transmission with artificial noise (AN) under
slow fading channels coexisting with randomly located eavesdroppers. We provide a …

In this paper we consider the secure transmission with multiple-input, single-output, single-
antenna eavesdropper (MISOSE) in fast fading channels where the transmitter knows …

We investigate the optimal physical-layer secure transmission with artificial noise in the
wiretap channel with N antennas at the transmitter, a single antenna at the receiver, and M …

The impact of quantized channel direction information (CDI) on the achievable secrecy rate
is studied for multiple antenna wiretap channels. By assuming that the eavesdropper's …

This paper investigates the power allocation problem for artificial noise (AN) secure
precoding systems, and proposes closed-form solutions for maximizing the achievable …

In this paper, we investigate the design of artificial-noise-aided secure multi-antenna
transmission in slow fading channels. The primary design concerns include the transmit …

The problem of secret communication between two nodes over a wireless link is considered,
where a passive eavesdropper may overhear the communication. It is desired that the …
