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 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.

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 with friendly full-duplex relay

2015 IEEE Wireless Communications and Networking Conference (WCNC), 2015
This paper considers the use of a friendly full-duplex (FD) relay to increase the secrecy rate over a fading channel between the legitimate source and destination in the presence of a naive or informed eavesdropper. Naive eavesdropper can only decode the received signals either from the source or from the relay, while informed eavesdropper can overhear

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 ...

The achievable secrecy rate of MISO wiretap channels

2011 International Conference on Wireless Communications and Signal Processing (WCSP), 2011
In this paper, we study the achievable secrecy rate of the multiple input single output (MISO) wiretap channel, which consists of a transmitter, a legitimate receiver and multiple eavesdroppers. The transmitter is equipped with multiple antennas, while the receiver and all the eavesdroppers each have a single antenna. We assume that the transmitter has

The Meta Distributions of Secrecy Rate for the Downlink NOMA Systems

IEEE Wireless Communications Letters, 2021
In this letter, the Meta distributions (MDs) of the secrecy rate in downlink non-orthogonal multiple access (NOMA) systems with randomly located eavesdroppers are investigated. Due to the complexity of calculation, the MDs for NOMA users are approximated by Beta approximation and the analytical expressions for the first two moments of conditional ...
