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 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.

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 Multiple-Antenna Eavesdropper
IEEE Transactions on Vehicular Technology, 2014This 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.

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 ...

Secrecy Rate of MISO Optical Wireless Scattering Communications
IEEE Transactions on Communications, 2018 We consider the secrecy rate for the multiple-input single-output optical wireless scattering communication, where the detected signal can be characterized by discrete photoelectrons. Assuming a legitimate receiver and an eavesdropper, we propose two secure communication protocols, the non-jamming protocol, and the cooperative jamming protocol, where ...

Secrecy Rate Beamforming for Multi-Cell SWIPT Networks
2016 IEEE Globecom Workshops (GC Wkshps), 2016 Considering a multicell network for secure wireless information and power transfer, this paper studies the joint design of transmit beamformers at the base stations (BSs) and receive signal splitting ratios at the end users' equipment (UEs). The primary concern in this work is the network internal security, where there may be a single multi-antenna ...

Secrecy rate with friendly full-duplex relay
2015 IEEE Wireless Communications and Networking Conference (WCNC), 2015This 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
