In order to formalize and extend on previous ad-hoc analysis and synthesis methods a theoretical treatment using vector representations of directional modulation (DM) systems is introduced and used to achieve DM transmitter characteristics. An orthogonal vector approach is proposed which allows the artificial orthogonal noise concept derived from information theory to be brought to bear on DM analysis and synthesis. The orthogonal vector method is validated and discussed via bit error rate (BER) simulations.read more

Directional Modulation-Enabled Secure Transmission with Intelligent Reflecting Surface
TL;DR: In this paper, the authors proposed a new secure transmission scheme which uses directional modulation with artificial noise and is aided by the intelligent reflecting surface (IRS), where the direct path and RIS-enabled reflect path carry the same confidential signal and can be coherently added at the desired position to maximize the total received power, while the received signals at other positions are distorted.
