This paper investigates secrecy rate optimization problems for a multiple-input-single-output
(MISO) secrecy channel in the presence of multiple multiantenna eavesdroppers …

This paper studies secrecy rate optimization in a wireless network with a single-antenna
source, a multi-antenna destination and a multi-antenna eavesdropper. This is an …

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 …

This work investigates the effect of finite-alphabet input constraint on the secrecy rate of a
multi-antenna wiretap channel. Most existing works have characterized maximum …

Secrecy on the physical layer is a promising technique to simplify the overall cross-layer
secrecy concept. In many recent works on the multiple antenna wiretap channel, perfect …

In satellite communication downlinks, physical layer security is challenging to achieve due to
their broadcasting nature and Line-of-Sight channel characteristics. This paper provides a …

Physical layer secrecy has attracted much attention in recent years due to its ability to
ensure communication secrecy with the use of channel coding and signal processing …

Physical layer security, or information-theoretic security, has attracted considerable attention
recently, due to its potential to enhance the transmission secrecy of wireless …
