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.

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 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 ...

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 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 ...
