Three Artificial-Noise-Aided Secure Transmission Schemes in Wiretap Channels

Yan, Shihao; Yang, Nan; Land, Ingmar; Malaney, Robert; Yuan, Jinhong


We examine the secrecy performance of three artificial-noise-aided secure transmission schemes, namely, the partially-adaptive, fully-adaptive, and on-off schemes. To this end, we provide new analysis to facilitate the optimization of the fraction ϕ of the transmit power allocated to the useful signal and redundancy rate RE. Surprisingly, our examination indicates that the partially-adaptive scheme, in which only the codeword rate RB varies with the instantaneous channel gains,...[Show more]
