Artificial Noise-Aided Physical Layer Security in Underlay Cognitive Massive MIMO Systems with Pilot Contamination
In this paper, a secure communication model for cognitive multi-user massive multiple-input multiple-output (MIMO) systems with underlay spectrum sharing is investigated. A secondary (cognitive) multi-user massive MIMO system is operated by using underlay spectrum sharing within a primary (licensed) multi-user massive MIMO system. A passive multi-antenna eavesdropper is assumed to be eavesdropp...
متن کاملPhysical Layer Security in Massive MIMO
We consider a single-cell downlink massive MIMO communication in the presence of an adversary capable of jamming and eavesdropping simultaneously. We show that massive MIMO communication is naturally resilient to no training-phase jamming attack in which the adversary jams only the data communication and eavesdrops both the data communication and the training. Specifically, we show that the sec...
متن کاملPhysical layer security of MIMO-OFDM systems by beamforming and artificial noise generation
In this paper we address physical layer security in MIMO frequency selective wireless channels in the presence of a passive eavesdropper, i.e., the associated channel is unknown to the transmitter. Signalling is based on orthogonal frequency division multiplexing (OFDM). Spatial beamforming and artificial noise broadcasting are chosen as the strategy for secure transmission. The contribution of...
متن کاملRobust Beamforming for Physical Layer Security in BDMA Massive MIMO
In this paper, we design robust beamforming to guarantee the physical layer security for a multiuser beam division multiple access (BDMA) massive multiple-input multiple-output (MIMO) system, when the channel estimation errors are taken into consideration. With the aid of artificial noise (AN), the proposed design are formulated as minimizing the transmit power of the base station (BS), while p...
متن کاملPilot Contamination in Small-Cell Massive MIMO Systems
The increasing demand for wireless data services requires massive network densification which is neither economically nor ecologically feasible. The concept of cell-size reduction provides an effective and simple solution to this problem. Small-Cell Networks (SCN) are one of the promising architectures based on this idea. Generally, a SCN is a cellular network where the size of the cells are ve...
