Secrecy Rate of Time Switched Transmit Diversity System
2011 IEEE 73rd Vehicular Technology Conference (VTC Spring), 2011Time switched transmit diversity (TSTD) system uses only one out of several transmit antennas at a time in order to exploit the benefit of transmit diversity while keeping the system simple by having only one RF chain. We show that while average rate of such a system remains similar to the capacity of the single transmit antenna, outage secrecy ...

Secrecy Rate Beamforming for Multi-Cell SWIPT Networks
2016 IEEE Globecom Workshops (GC Wkshps), 2016Considering 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 of MISO Optical Wireless Scattering Communications
IEEE Transactions on Communications, 2018We 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 ...

Optimization of secrecy rate in cooperative device to device communications
2017 IEEE 30th Canadian Conference on Electrical and Computer Engineering (CCECE), 2017In this paper, a cooperative device to device (D2D) communication system is studied while two transmitting devices communicate with one destination device in the presence of a passive eavesdropper. The second transmitting device cooperates with the first transmitting device and hence the transmission takes place is two phases.

On Ergodic Secrecy Rate for Gaussian MISO Wiretap Channels
IEEE Transactions on Wireless Communications, 2011A Gaussian multiple-input single-output (MISO) wiretap channel model is considered, where there exists a transmitter equipped with multiple antennas, a legitimate receiver and an eavesdropper, each equipped with a single antenna. We study the problem of finding the optimal input covariance that maximizes the ergodic secrecy rate subject to a power ...

Going beyond Secrecy Rate via Information Jamming
2018 IEEE Global Communications Conference (GLOBECOM), 2018Cooperative jamming approach has been commonly used in the field of physical layer security to achieve a good secrecy rate of wireless networks. In this approach, the Gaussian noise signal sent by a friendly jammer can disrupt the reception of the eavesdropper, however, it may also interfere with the legitimate receiver.

Efficient Algorithm for Selecting Secrecy Rate Maximizing Antennas
IEEE Communications Letters, 2013Antenna selection (AS) is poised to provide solutions to hardware complexity issues while guaranteeing untappable information flow. We investigate the AS problem set up in the context of linear precoder design for secrecy rate maximization of a multiple-input single-output system. The original problem is both non-tractable and nonconvex.
