On Ergodic Secrecy Rate for Gaussian MISO Wiretap Channels

IEEE Transactions on Wireless Communications, 2011
A 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 ...

On ergodic secrecy rate of multiuser MISO downlink wiretap channel

2014 12th International Conference on Signal Processing (ICSP), 2014
In this paper, we consider the problem of secure communication in multiuser downlink wiretap networks where there exist a base-station (BS) equipped with multiple antennas, multiple legitimate receivers and a passive eavesdropper. The transmitter simultaneously transmits an information signal and artificial noise (AN) separately to the intended ...

Ergodic Secrecy Rate for Gaussian MISO Wiretap Channels with Non-Trivial Covariance

2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
A 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 achieves ergodic secrecy rate subject to a power constraint

Ergodic Secrecy Rate of K -user MISO Broadcast Channel with Improved Random Beamforming

2020 IEEE Wireless Communications and Networking Conference (WCNC), 2020
In this paper, we study the secrecy performance of multiple-input single-output (MISO) wiretap channel with random beamforming (RB), where the eavesdropper is equipped with multiple antennas. In traditional RB schemes, the transmitter utilizes only one antenna to emit information signal and adopts the rest antennas to produce a random beamforming ...

Ergodic Achievable Secrecy Rate of Multiple-Antenna Relay Systems With Cooperative Jamming

IEEE Transactions on Wireless Communications, 2016
This paper investigates the ergodic achievable secrecy rate (EASR) of multiple-antenna amplify-and-forward relay systems, where one eavesdropper can wiretap the relay. To reveal the capability of the multiple-antenna relay in improving the secrecy performance, we derive new tight closed-form expressions of the EASR for three secure transmission schemes:

Ergodic secrecy sum rate for multiuser MIMO downlink systems using block diagonalization

2016 IEEE Conference on Communications and Network Security (CNS), 2016
To date, the achievable ergodic secrecy sum rate has been studied for multiuser MIMO downlink systems with single-antenna receivers only. In this paper, we study multiuser MIMO downlink systems with multiple-antenna receivers and an external single-antenna eavesdropper to be kept ignorant of the transmitted messages.

On the Ergodic Secrecy Rate of Cooperative Decode-and-Forward Relay Networks

2014 IEEE Military Communications Conference, 2014
In this article, we develop a unified analytical framework for investigation of the ergodic secrecy rates of cooperative decode-and-forward relay networks in a myriad of fading environments. We utilized an exponential-type integral representation for the logarithmic function to derive an approximate expression for the ergodic secrecy rates of ...

Achievable Ergodic Secrecy Rate in Bursty Interference Channels With Opportunistic User Scheduling

IEEE Transactions on Communications, 2019
This paper studies secure transmissions in a bursty interference channel constructed by opportunistic user scheduling. To improve the physical layer security, we propose a signal-to-noise-plus-interference ratio (SINR) based opportunistic transmission scheme and mathematically analyze the ergodic secrecy rate per transmitter-receiver pair.
