In this paper the fading multiple antenna (MIMO) wire-tap channel is investigated under
short term power constraints. The secret diversity gain and the secret multiplexing gain are …

We consider two fundamental multi-user channel models: the multiple-input multiple-output
(MIMO) wiretap channel with one helper (WTH) and the MIMO multiple access wiretap (MAC …

In this paper, we address the finite Signal-to-Noise Ratio (SNR) Diversity-Multiplexing
Tradeoff (DMT) of the Multiple Input Multiple Output (MIMO) wiretap channel, where a Zero …

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

In this paper, we address the finite Signal-to-Noise Ratio (SNR) Diversity-Multiplexing
Tradeoff (DMT) of the Multiple Input Multiple Output (MIMO) wiretap channel, where a Zero …

A two-transmitter Gaussian multiple access wiretap channel with multiple antennas at each
of the nodes is investigated. The channel matrices of the legitimate users are fixed and …

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

Secret sharing over the fast-fading MIMO wiretap channel is considered. A source and a
destination try to share secret information over a fast-fading MIMO channel in the presence …

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 …

We consider the General Gaussian Multiple Access Wire-Tap Channel (GGMAC-WT). In this
scenario, multiple users communicate with an intended receiver in the presence of an …
