A hybrid multi-state orbital angular momentum-multi pulse-position modulation ( $N$ OAM-MPPM) scheme over gamma-gamma free-space optical ( ${\Gamma \Gamma }$ -FSO) channel is studied in this paper. In our study, all atmospheric and pointing error imp

Orbital angular momentum-shift keying (OAM-SK), which is the rapid switching of OAM modes, is vital but seriously impeded by the deficiency of OAM demodulation techniques, particularly when videos are transmitted over the system. Thus, in this paper,

A new power efficient technique, that combines $\boldsymbol{N}$ -level multipulse pulse-position modulation with $\boldsymbol{L}$ -level quadrature-amplitude modulation, denoted by $\boldsymbol{N}$ MPPM- $\boldsymbol{L}$ QAM, is proposed. Its constra
