DFT-based multi-directions directional modulation
(Institute of Electrical and Electronics Engineers, 2019)In this letter, a physically secure multi-directions directional modulation scheme is proposed. The scheme provides an adaptive beam-width assignment, where each user is granted a different beam width based on its channel ... -
Energy and spectral-efficient lens antenna subarray design in MmWave MIMO Systems
(IEEE-Institute Electrical Electronics Engineers Inc, 2022)Lens antenna subarray (LAS) is one of the recently introduced technologies for future wireless networks that significantly improves the energy efficiency of multiple-input multiple-output (MIMO) systems while achieving ... -
Physical layer authentication scheme in beamspace MIMO systems
(Institute of Electrical and Electronics Engineers Inc., 2022)The broadcast nature of wireless communication makes it vulnerable to various security threats such as spoofing attacks. Physical layer (PL) authentication has emerged as a promising and powerful approach to secure future ... -
Secure spatial multiple access using directional modulation
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)In this paper, we introduce a secure multiple access scheme, which exploits the multipath structure of the channel to create a multi-user interference environment. The generated interference enables legitimate users to ...
