In this paper, we propose a physical layer security scheme that exploits novel index modulation (IM) technique for coordinate interleaved orthogonal designs (CIOD). Utilizing the diversity gain of CIOD transmission, proposed scheme, named CIOD-IM, provides an improved spectral efficiency by means IM. order to provide satisfactory secrecy rate, design particular artificial noise matrix, which do...

Dual function radar communications (DFRC) systems are attractive technologies for autonomous vehicles, which utilize electromagnetic waves to constantly sense the environment while simultaneously communicating with neighbouring devices. An emerging approach implementing DFRC is embed information in waveforms via index modulation (IM). Implementation of schemes vehicular gives rise strict constr...
