Orbital Angular Momentum Multiplexing in Highly Reverberant Environments
arXiv:2001.11953 · doi:10.1109/LMWC.2019.2952975
Abstract
Previous studies on orbital angular momentum (OAM) communication mainly considered line-of-sight 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 conventional multiple-input multiple-output (MIMO) system.
