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 based on dual-function radar-communication system
TL;DR: In this article , a beam weight vector set is established to achieve the security of information transmission, and the remaining weight vectors are derived from it, by minimizing the differences between them, so that the transmitting beams shaped by the designed weight vector are almost the same in radar main lobe, but differ in the amplitudes and phases towards the direction of intended communication receivers.

Power allocation strategies with per-antenna for secure directional modulation
TL;DR: Simulation results show that the proposed two methods have better SR performance than the conventional PA factor scheme, and the proposed Max-SLNR-ANLNR method forms a single energy main peak at Eve position, which indicates it realizes precise jamming.
