Three mathematicians have laid out proof that solves a long-standing problem in mathematics. Even the mathematician—an Abel ...
Abstract: This paper proposes a three-dimensional (3D) interfer-ometer direction-finding (DF) method to address the reduced accuracy of conventional two-dimensional (2D) interferometer DF methods in ...
Abstract: In this paper, we study the beamforming schemes via the novel frequency diverse array (FDA) on enhancing covert communications performance. We first consider the ideal scenario where the ...
