Secrecy diversity in MISOME wiretap channels

Abstract: The use of multiple-antenna arrays can leverage the physical-layer security of wireless systems. It is therefore impor tant to characterize such systems in a realistic situation where we can apply the so-called artificial-noise solution in multiple antenna systems to enhance the communication confidentiality by only exploiting a fading nature of wireless environments. In this paper, we consider secure communication over a multiple input single-output Rayleigh-fading channel in the presence of a multiple-antenn… Show more

“…An example of secure transmission schemes under perfect MCSI and statistical ECSI is given in [43] where the authors consider a MISOME channel and define a practical secrecy metric (instead of an information theoretic one), which quantifies the symbol error probability of the confidential data, and show that in the absence of artificial noise, secrecy diversity (i.e., the high-SNR slope of their defined metric) vanishes. This result underlines the importance of artificial noise injection in these scenarios.…”
