Abstract

Media-based modulation (MBM) concept is exploited to increase physical layer (PHY) security in the presence of an illegitimate listener. A precoding design is developed to increase the mutual secrecy rate of MBM, and the secrecy mutual information expressions are derived. The provided analyses and numerical results have also shown that MBM is a perfect candidate for PHY security by providing the maximum achievable secrecy mutual information, even in the presence of channel estimation errors.
