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 receiver antenna apertures. By generating and transmitting multiplexed OAM beams, the system achieves spatial overlapping at the receiver aperture plane. This technique demonstrates compatibility and complementarity of OAM multiplexing and traditional spatial multiplexing with MIMO processing, improving the capabilities of LoS systems.
Benefit
- Enables high-speed millimeter-wave communication
- Increases signal quality and performance
- Reduces interference from other OAM channels
- Improves Bit Error Rate (BER) performance
Market Application
Line of Sight (LoS) communications systems are useful in many situations, particularly in emergencies when other means of communication are unavailable. LoS systems work best with large bandwidth. The conventional method of increasing bandwidth involves multiple spatially separated transmitter antennas and receivers, which reduces crosstalk. However, implementation is costly, and expenses rise with the number of transmitters and receivers. Thus, there is a need for more cost-effective solutions to increase LoS system bandwidth.
