Communication using orbital angular momentum (OAM) modes has recentlyreceived a considerable interest in free space optical (FSO) communications.Propagating OAM modes through free space may be subject to atmosphericturbulence (AT) distortions that cause signal attenuation and crosstalk whichdegrades the system capacity and increases the error probability. In thispaper, we propose to enhance the OAM FSO communications in terms of bit errorrate and spectral efficiency, for different levels of AT regimes. Theperformance gain is achieved by introducing orthogonal frequency divisionmultiplexing (OFDM) with index modulation technique to the OAM FSO system.
