Jamming-Aided Secure Communication in Massive MIMO Rician Channels
, 2015 In this paper, we investigate the artificial noise-aided jamming design for a transmitter equipped with large antenna array in Rician fading channels. We figure out that when the number of transmit antennas tends to infinity, whether the secrecy outage ...

On the Analysis of Secrecy Outage Probability Using Average Channel Capacity
Sakarya University Journal of Science, 2020 In this article, we analyze the outage probability of physically secure wireless signal transmission in fading envi-ronments where both primary and eavesdropper channels are subject to generalized fading. We propose a novel approach using the average channel capacity of the primary channel and that of the eavesdropper channel to the outage probability ...

Outage Constrained Robust Secure Transmission for MISO Wiretap Channels [PDF]
, 2013 In this paper we consider the robust secure beamformer design for MISO wiretap channels. Assume that the eavesdroppers' channels are only partially available at the transmitter, we seek to maximize the secrecy rate under the transmit power and secrecy ...

Location-Based Beamforming for Rician Wiretap Channels
, 2015 We propose a location-based beamforming scheme for wiretap channels, where a source communicates with a legitimate receiver in the presence of an eavesdropper.

Secrecy Outage Performance Analysis for Cooperative NOMA Over Nakagami-
IEEE Access, 2019 In this paper, we investigate the secrecy outage performance of a typical cooperative downlink non-orthogonal multiple access (NOMA) system over Nakagami-m fading channel, in which the base station transmits a superimposed signal to two users via a relay.
