The technique relies on injection of colored noise whose power spectral density has the least match with the spectrum of the main channel in a certain sense. By evaluation of an achievable secrecy rate, we demonstrate that the proposed AN injection based solution results in a considerable improvement over the existing approaches, especially when the eavesdropper works at high signal-to-noise ratios (SNRs).EnglishArtificial noiseFinite-state wiretap channelInter-symbol interferencePhysical layer securityConference Paper10.1109/ICT.2018.8464866
