Robust Outage Secrecy Rate Optimizations for a MIMO Secrecy Channel

IEEE Wireless Communications Letters, 2015
This letter investigates robust secrecy rate optimization techniques for a multiple-input-multiple-output (MIMO) wiretap channel in the presence of a multiantenna eavesdropper. In particular, two robust secrecy rate optimization problems are studied: robust power minimization with an outage secrecy rate constraint and robust secrecy rate maximization ...

Secrecy Rate Optimizations for a MIMO Secrecy Channel With a Multiple-Antenna Eavesdropper

IEEE Transactions on Vehicular Technology, 2014
This paper studies different secrecy rate optimization problems for a multiple-input–multiple-output (MIMO) secrecy channel. In particular, we consider a scenario where a communication through a MIMO channel is overheard by a multiple-antenna eavesdropper.

Secrecy Rate Analysis for the Cooperative Communications

2023 12th International Conference on Awareness Science and Technology (iCAST), 2023
Due to the character of low cost and easily to implemented, the cooperative communication is the future tendency. Three fundamental mode, Amplify-and-Forward (AF) mode, Decode-and-Forward (DF) mode and Compress and Forward (CF) mode are employed to the system.

Secrecy Rate Optimizations for a MIMO Secrecy Channel With a Cooperative Jammer

IEEE Transactions on Vehicular Technology, 2015
In this paper, we study different secrecy rate optimization techniques for a multiple-input–multiple-output (MIMO) secrecy channel, where a multiantenna cooperative jammer is employed to improve secret communication in the presence of a multiantenna eavesdropper.

Maximum secrecy rate in inhomogeneous poisson networks

2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017
The impressive growth of secrecy-sensitive wireless applications calls for methods to complement traditional cryptography. In particular, physical-layer security is attractive to enhance communication confidentiality by exploiting the characteristics of the wireless environment.

Ergodic Secrecy Rates of Secure Wireless Communications

2014 IEEE Military Communications Conference, 2014
Two unified analytical frameworks that facilitate the evaluation of the ergodic secrecy rates of Wyner wiretap channel in generalized fading environments without/with diversity receivers are developed. In contrast to prior work that is limited to only the Rayleigh fading environment, our new formulas expressed in terms of only the moment generating ...

MIMO multi-user secrecy rate analysis

2014 IEEE International Conference on Communications (ICC), 2014
In this paper, we consider the broadcast channel with confidential messages and eavesdroppers (BCCE), where a multi-antenna base station simultaneously communicates to multiple potentially malicious users, in the presence of external eavesdroppers randomly located according to a Poisson point process (PPP).

Secrecy Rate Pair Constraints for Secure Throughput

2014 IEEE Military Communications Conference, 2014
Physical layer security, which is an alternative to traditional cryptographic methods, has emerged as a promising candidate to protect wireless transmissions from an eavesdropper. An important measure of physical layer security is the secrecy outage: the event when the instantaneous secrecy capacity, which for the considered scenario is the difference ...

Secrecy Rate Analysis Against Aerial Eavesdropper

IEEE Transactions on Communications, 2019
This paper studies the threat that an aerial eavesdropper can pose to terrestrial wireless communications, from an information-theoretic point of view. The achievable ergodic and the average $\epsilon $ -outage secrecy rates with no channel state information at the transmitter (i.e., with no CSIT) are analyzed for a transmitter–receiver pair on ...
