Secrecy wireless information and power transfer with MISO beamforming (2013, background): “The reason is that energy beams in this paper will also play an important role of artificial noise (AN) [7] to facilitate the secret information transmission to the IR by interfering with the ERs that may eavesdrop the IR’s message.”
Optimal Cooperative Jamming to Enhance Physical Layer Security Using Relays (2011, methodology): “To improve the secrecy rate under unfavorable conditions, a possible approach is to use multiple-input multiple-output (MIMO) systems where multiple antennas at the transmitter and receiver allow the use of beamforming to steer a null to the eavesdropper [3], or the generation of artificial noise in”
QoS-Based Transmit Beamforming in the Presence of Eavesdroppers: An Optimized Artificial-Noise-Aided Approach (2011, background): “It is worthwhile to point out that most existing endeavors assume isotropic AN; i.e., the AN covariance is chosen as , where is the orthogonal complement projector of , and is a scale factor determining the power invested on AN [24], [25], [28].”
Improving Physical Layer Secrecy Using Full-Duplex Jamming Receivers (2013, background): “When the transmitter has multiple antennas, this can be achieved by having the transmitter embed in its transmission artificial noise, [6]–[8], which can be designed to avoid the legitimate receiver and only affect the eavesdroppers [6], [7].”
