We consider the physical layer security in a multi-user massive multiple-input multiple-output system, where an eavesdropper (Eve) can intercept the information intended for any of the legitimate users. Several remote radio heads (RRHs), each equipped with massive antennas, are deployed to create the distributed antenna system (DAS). With the cooperative maximum-ratio transmission, we propose three...
The physical layer security in a multi-user massive multiple-input multiple-output (MU-Massive-MIMO) system is considered in this paper, where a hidden eavesdropper (Eve) may eavesdrop the information signal of any legitimate user. Two distributed antenna system (DAS) aided power-saving transmit strategies are evaluated: 1) the autonomous full (AF) transmission with explicit artificial noise (AN),...
We consider in this paper the physical layer security of multi-pair communication in massive MIMO aided amplify-and-forward (AF) relaying, where an eavesdropper (Eve) may intercept the information intended to any of the destinations. We derive closed-form deterministic equivalents of the end-to-end signal to interference-plus-noise ratios of legitimate users and Eve. We assume that the AF processing...
We consider in this paper the physical layer security in multi-user massive multiple-input multiple-output (MU-Massive-MIMO) system, where an eavesdropper (Eve) is assumed to be able to intercept the information intended to any of the users. Distributed antenna sets, commonly known as remote radio heads (RRHs), are deployed at the base station, which enables autonomous power allocation between the...
