Previous studies on orbital angular momentum (OAM) communication mainly considered line-of-sight (LOS) environments. In this letter, however, it is found that OAM communication with high-order modulation can be achieved in highly reverberant environments by combining the OAM multiplexing with a spatial equalizer. The OAM multiplexing exhibits comparable performance of the conventional multiple-input–multiple-output (MIMO) system.
