Abstract
A system includes a transmitter having a first transmit device having a first transmit antenna and a first OAM multiplexer designed to receive two input signals and to convert the input signals to orthogonal OAM beams. The first transmit antenna is designed to transmit a first output signal that includes the OAM beams. The transmitter also includes a second transmit device that functions in a similar manner as the first transmit device. A receiver includes a first receive device having a first receive antenna designed to receive the first output signal and a first OAM demultiplexer designed to convert the first output signal to received signals corresponding to the input signals. The receiver also includes a second receive device having similar features as the first receive device. The receiver also includes a MIMO processor designed to reduce interference between the received signals.
