Energy Efficient Dynamic Directional Modulation with Electrically Small Antennas
(2022)This letter proposes a compact and energy efficient Directional Modulation (DM) scheme for small and power constrained devices (e.g. Internet of Things wireless sensors). The scheme uses a uniform circular array of monopole ... -
Physical Limitation of Range-Domain Secrecy Using Frequency Diverse Arrays
(2020)In this paper, the concept and recent development of exploiting frequency diverse array (FDA) and its variants for the physical-layer wireless security have been revisited and carefully examined. Following rigorous analytical ...
