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.

When describing puzzles related to dice, it is always necessary to mention the configuration at the cost of repetition. If the die is standard, the 6 is always opposite the 1, the 5 is always opposite ...

Abstract: By combining the offset center of gravity (OCOG) estimation with the front-end automatic gain control (AGC), a closed-loop tracking OCOG-AGC algorithm is proposed to address the problem of ...
