Abstract: Automatic modulation classification (AMR) is essential for receivers to demodulate signals in communication systems. Currently, various portable devices are capable of receiving a large ...

Abstract: In this work, a method for increasing the efficiency-bandwidth product of an electrically small antenna (ESA) by using spatially discrete traveling-wave modulation (SDTWM) is introduced.

Researchers developed a microscopic theory in which intra-valley, finite-momentum pair-density waves generate the Kekulé ...
