Abstract: This paper presents a D-band direct-digital transmitter that employs RF-DACs to perform modulation in the RF domain. It achieves 64-QAM with a maximum data rate of $48 \mathrm{~Gb} / \mathrm ...
Abstract: This paper presents a novel flat-top directional modulation (DM) synthesis approach utilizing constant amplitude antenna arrays. Unlike traditional modulation schemes, the proposed method ...
