Abstract: To improve the estimation accuracy of two-dimensional (2D) direction-of-arrival (DOA) of uniform rectangular array, and increase the degrees of freedom of the array, this paper proposes a ...

Abstract: Analytical expression of transmission for the orbital angular momentum (OAM) communication using loop antenna arrays and paraboloids is derived to achieve a communication distance of 100 m.

Autoregressive transformers serialize two-dimensional grids into one-dimensional token sequences, destroying spatial locality and committing to each cell irrevocably. We present the Grid Diffusion ...
