In this letter, a novel space shift keying (SSK)-based communication scheme for secrecy enhancing is proposed. In the proposed scheme, one legitimate user and one eavesdropper exist as the receivers. The secrecy rate (SR) performance is achieved by applying the designed artificial noise (AN) to the traditional SSK system. In this way, we can effectively interfere the eavesdropper while maintaining the communication for the legitimate user. Results from the simulations demonstrate that the proposed scheme outperforms the traditional scheme in terms of the SR.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
