Ergodic secrecy sum rate maximization in downlink sparse code multiple access network
2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC), 2017Sparse code multiple access (SCMA) has been recognized as a promising candidate technique for fifth generation (5G) cellular network to improve spectral efficiency (SE). In this paper, physical layer security (PLS) in a downlink single-input single-output (SISO) SCMA system is investigated, which includes one base station (BS), multiple legitimate ...

Ergodic Secrecy Rate of Randomly Deployed Cellular Networks Enhanced by Artificial Noise
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017As 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 ...

Ergodic Secrecy Rate of $K$-User MISO Broadcast Channel With Improved Random Beamforming
IEEE Transactions on Vehicular Technology, 2019In this paper, we study the secrecy performance of a $K$ -user multi-input single-output (MISO) broadcast channel with random beamforming (RB), where the transmitter is equipped with $N$ antennas, and the eavesdropper has $N_e$ antennas.

Ergodic Secrecy Sum-Rate for Downlink Multiuser MIMO Systems With Limited CSI Feedback
IEEE Communications Letters, 2014This paper investigates the ergodic secrecy sum-rate for the downlink multiuser MIMO system with independent confidential messages, each of which is intended for one of the users and should keep secret from others. We adopt zero-forcing beamforming with limited channel state information (CSI) feedback at the transmitter, and derive the closed-form ...

2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011
We consider the problem of secure communication in wireless fading channels in the presence of quantized version of the receivers channel sate information at transmit side. The transmitter has multiple antennas and is able to simultaneously transmits an information bearing signal and artificial noise.

2019 International Conference on Advanced Technologies for Communications (ATC), 2019
In this paper, we investigate the secrecy performance of massive multiple-input multiple-output (MIMO) nonorthogonal multiple access (NOMA) networks with the presence of a passive eavesdropper. Based on the estimated channel state information in an uplink training phase, the base station precodes the confidential information using zero-forcing ...

IEEE Communications Letters, 2014
In this letter, we study the ergodic secrecy sum-rate of a multiuser downlink system achievable by using the regularized zero-forcing precoding based on imperfect channel estimation. The channels between the base station and users are modeled as fading channels with different spatial correlations and line-of-sight components.

IEEE Transactions on Vehicular Technology, 2016
Security and privacy have become increasingly critical demands in wireless networks, which, however, are particularly susceptible to eavesdropping attacks due to the broadcast nature of radio signals. This paper considers the problem of secure communication in the multiuser downlink with a passive eavesdropper (Eve), whose channel state information ...
