Abstract: In this paper, we study the downlink precoding of spatial non-stationary (SnS) extremely large-scale multiple-input multiple-output (XL-MIMO) in the near-field channel with uniform spherical ...
Abstract: Simultaneous consideration of uniform degrees of freedom (uDOF) and mutual coupling is a key focus in sparse array design. To reduce mutual coupling and increase degrees of freedom (DOF), a ...
