We analyze the physical layer (PHY) security of a communication scheme consisting of a
multiple antenna transmitter with a single radio frequency (RF) chain using transmit antenna …

This paper advocates physical layer security of maximal ratio combining (MRC) in wiretap
two-wave with diffuse power fading channels. In such a wiretap channel, we consider that …

We analyze the impact of antenna correlation on secrecy performance of multiple-input
multiple-output wiretap channels where transmitter employs transmit antenna selection …

We propose and analyze transmit antenna selection (TAS) to enhance physical layer
security in a wiretap channel with NA antennas at the transmitter, NB antennas at the …

We consider the problem of secure communication in wireless fading channels in the
presence of non-colluding passive eavesdroppers. The transmitter has multiple antennas …

We address physical layer security in multiple-input-multiple-output (MISO) communications
in the presence of an unknown passive eavesdropper. Beamforming and artificial noise …

As a complement to high-layer encryption techniques, physical layer security has been
widely recognized as a promising way to enhance wireless security by exploiting the …

This letter studies the physical-layer security of a multi-antenna transmission system in the
presence of Poisson distributed eavesdroppers. The transmission secrecy outage …

We study physical-layer security in wireless ad hoc networks and investigate two types of
multi-antenna transmission schemes for providing secrecy enhancements. To establish …

We propose and analyze transmit antenna selection with receive generalized selection
combining (TAS/GSC) for physical layer security enhancement in multiple-input multiple …
