Joint Precoder and Reflector Design for RIS-assisted Multi-user OAM Communication Systems
Xiaoyan Ma, Yufei Zhao, Haixia Zhang +2
Orbital angular momentum (OAM) can enhance the spectral efficiency by multiplying a set of orthogonal modes on the same frequency channel. To maintain the orthogonal among differen…
