Ergodic Secrecy Rate Analysis of Ultra-Dense Networks with Multiple Antennas

ICC 2021 - IEEE International Conference on Communications, 2021
Ultra-Dense Networks (UDNs), where Small Cells (SCs) will be deployed in very high densities, are considered as a leading promising technology in 5G and beyond. Such SCs being equipped with multiple antennas can further enhance the achievable performance.

Achievable ergodic secrecy rate for MIMO SWIPT wiretap channels

2015 IEEE International Conference on Communication Workshop (ICCW), 2015
In 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.

Ergodic Secrecy Rate for Multiple-Antenna Wiretap Channels With Rician Fading

IEEE Transactions on Information Forensics and Security, 2011
A Gaussian multiple-antenna wiretap channel model is considered, where there exists a transmitter equipped with multiple antennas, a legitimate receiver equipped with a single antenna, and an eavesdropper equipped with multiple antennas. We study the problem of finding the optimal input covariance that maximizes the ergodic secrecy rate subject to a ...

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 ...

On the ergodic secrecy capacity of the wiretap channel under imperfect main channel estimation

, 2011
The ergodic secrecy capacity of the wiretap channel is known when the main channel (between the transmitter and the legitimate receiver) state information (CSI) is perfect at the transmitter and the coherence period is sufficiently large to enable random

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 Secrecy Rate of Randomly Deployed Cellular Networks Enhanced by Artificial Noise

2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017
As the future cellular networks tend to be randomly deployed and equipped with more antennas, we study the enhanced secrecy rate of multiple- input multiple-output (MIMO) systems with a stochastic geometry approach. To avoid intractable computational complexity and to have a deep insight into the security performance of such networks, we derive a ...
