2016-062 - Free-Space Optical Communications Using Orbital-Angular-Momentum Multiplexing and MIMO-Based Spatial Multiplexing

5G communication Transceivers Last mile access Abstract USC’s solution increases the capacity of Free-Space Optical (FSO) communications by combining Multiple- input-multiple-output (MIMO) based spatial multiplexing with orbital angular momentum (OAM) multiplexing. MIMO signal processing with OAM beam orthogonality can phenomenally reduce...

2015-082 - 16 Gbit/s mm-wave Communications with MIMO Processing

LoS communication systems Cell phone communication systems Emergency communication systems Abstract USC researchers have developed a high-speed mm-wave communication link achieving a data rate of 16 Gbit/s. The link utilizes Multiple-Input Multiple-Output (MIMO) processing of two Orbital Angular Momentum (OAM) modes on each of the transmitter and...
