Vector representation of directional modulation transmitters [PDF]
, 2014 Directional Modulation (DM) is a recently proposed technique for securing wireless communication. In this paper we point out that modulation-directionality is a consequence of varying the beamforming network, either in baseband or in the RF stage, at the

New Journal of Physics, 2007 A search technique locating network modules, i.e., internally densely connected groups of nodes in directed networks is introduced by extending the Clique Percolation Method originally proposed for undirected networks. After giving a suitable definition for directed modules we investigate their percolation transition in the Erdos-Renyi graph both ...

Design of OAM Beam Directional Modulation Signal in Communication and Guidance Integration [PDF]
Radioengineering, 2020 An orbital angular momentum directional modulation (OAM-DM) signal is proposed for communication and guidance integration. This signal is transmitted by a uniform circular antenna array (UCA). We divide the array into odd and even antenna groups.

Transmitted Data Security in Non-Orthogonal Multiple Access Networks with Directional Modulation Based on User Location [PDF]
International Journal of Information and Communication Technology Research, 2023 In Non-orthogonal multiple access, a user with a weaker channel gain is assigned more power than a user with a stronger channel. This type of power allocation allows the strong user (SU) to apply the successive interference cancellation (SIC) method that
