Ergodic Secrecy Rates of Secure Wireless Communications
2014 IEEE Military Communications Conference, 2014Two 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 ...

Achievable ergodic secrecy rate for MIMO SWIPT wiretap channels
2015 IEEE International Conference on Communication Workshop (ICCW), 2015In this paper, we study the multiple-input multiple-output (MIMO) wiretap channel performing simultaneous wireless information and power transfer (SWIPT), where there are a multiple-antenna base station (BS), a multiple-antenna information decoding (ID) user, and a multiple-antenna energy harvesting (EH) user.

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 ...

On ergodic secrecy rate of multiuser MISO downlink wiretap channel
2014 12th International Conference on Signal Processing (ICSP), 2014In 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, 2010A 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), 2020In 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, 2016This 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), 2016To 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.
