    OAM-based reconfigurable doppler shifts enable PAPR reduction for multi-carrier doppler diversity by Zhao, Yufei, Ge, Yao, Yang, Zhaojie, Ju, Gaohua, Ma, Lu, Lu, Yilong, Guan, Yong Liang

    Published 2023
    “…In a recent study, we discovered that even when the transceivers are stationary, a specific spatial Doppler shift can be generated by rotating the wavefront structure of the OAM helical beams. Furthermore, arbitrary integer rotational OAM Doppler shifts can be realized flexibly by using the recently popular digital encoding metasurfaces. …”
