Duke engineers introduce Argus, a robot with no front, no back and 20 eyes, as proof-of-concept for a new design principle called dynamic symmetry. Symmetry is everywhere in nature, from the bilateral ...
Abstract: Since hybrid beamforming (HBF) can approach the performance of fully-digital beamforming (FDBF) with much lower hardware complexity, we investigate the HBF design for beam-hopping (BH) low ...
