TLDR
This paper proposes linear precoder designs exploiting statistical channel knowledge at the transmitter in a multiple-input multiple-output (MIMO) wireless system, using a convex optimization framework to minimize the Chernoff bound on the pairwise error probability (PEP) between a pair of block codewords.Citations

On Cooperative Relaying Schemes for Wireless Physical Layer Security
TL;DR: A cooperative wireless network in the presence of one or more eavesdroppers, and node cooperation for achieving physical (PHY) layer based security is considered, and an analytical solution is obtained for the DF scheme with a single eavesdropper and the multivariate problem is reduced to a problem of one variable.

Worst-Case Robust MIMO Transmission With Imperfect Channel Knowledge
Jiaheng Wang,Daniel P. Palomar +1 more
TL;DR: This paper considers robust transmit strategies, against the imperfectness of the channel state information at the transmitter (CSIT), for multi-input multi-output (MIMO) communication systems, and finds that the optimal transmit directions are just the right singular vectors of the nominal channel under some mild conditions.

Statistically Robust Design of Linear MIMO Transceivers
TL;DR: This work considers the robust design of linear MIMO transceivers with perfect CSI either at the transmitter or at both sides of the link, and considers the design problem where the imperfect CSI consists of the channel mean and covariance matrix.

On Ergodic Secrecy Rate for Gaussian MISO Wiretap Channels
Jiangyuan Li,Athina P. Petropulu +1 more
TL;DR: This paper addresses the general case in which the eavesdropper and legitimate channels have nontrivial covariances, and shows that when full information on the legitimate channel is available to the transmitter, the optimal input covariance has always rank one.

Convex Optimization
Stephen Boyd,Lieven Vandenberghe +1 more
TL;DR: In this article, the focus is on recognizing convex optimization problems and then finding the most appropriate technique for solving them, and a comprehensive introduction to the subject is given. But the focus of this book is not on the optimization problem itself, but on the problem of finding the appropriate technique to solve it.

A simple transmit diversity technique for wireless communications
TL;DR: This paper presents a simple two-branch transmit diversity scheme that provides the same diversity order as maximal-ratio receiver combining (MRRC) with one transmit antenna, and two receive antennas.

Capacity of Multi‐antenna Gaussian Channels
TL;DR: In this paper, the authors investigate the use of multiple transmitting and/or receiving antennas for single user communications over the additive Gaussian channel with and without fading, and derive formulas for the capacities and error exponents of such channels, and describe computational procedures to evaluate such formulas.
