Precoding has been conventionally considered as an effective means of mitigating or
exploiting the interference in the multiantenna downlink channel, where multiple users are …

Directional modulation (DM) is an emerging technology for securing wireless
communications at the physical layer. This promising technology, unlike the conventional …

Wireless communication provides a wide coverage at the cost of exposing information to
unintended users. As an information-theoretic paradigm, secrecy rate derives bounds for …

An orthogonal vector approach is proposed for the synthesis of multi-beam directional
modulation (DM) transmitters. These systems have the capability of concurrently projecting …

In this paper, directional modulation (DM) is investigated to enhance physical layer security.
Practical transmitter designs are exploited under imperfect channel state information (CSI) …

In this paper, metrics for assessing the performance of directional modulation (DM) physical-
layer secure wireless systems are discussed. In the paper DM systems are shown to be …

By modification of the classical retrodirective array architecture, a directional modulation
(DM) transmitter can be realized without the need for synthesis. Importantly, through …

This study proposes a range‐and angle‐dependent directional modulation (DM) scheme
using frequency diverse array (FDA) for secure wireless communications. It uses uniform …

In this study, a far‐field power pattern separation approach is proposed for the synthesis of
directional modulation (DM) transmitter arrays. Separation into information patterns and …

By identifying the similarities and differences between multiple-input-multiple-output (MIMO)
and directional modulation (DM) technologies, a new approach for the synthesis of DM …
