Patent attributes
In an OAM multiplexing communication system in which an M-UCA is provided in each of a transmitting station and a receiving station, signals in a plurality of OAM modes are generated and transmitted from each UCA of the transmitting station, signals in the plurality of OAM modes are received and demultiplexed by each UCA of the transmitting station, and streams of the number of UCAs×the number of OAM modes are subjected to spatial multiplex transmission, in which the transmitting station includes a signal processing unit generating the streams to be transmitted in the plurality of OAM modes from each of the UCAs of the M-UCA, and the receiving station includes a signal processing unit receiving the signals in the plurality of OAM modes demultiplexed by each of the UCAs of the M-UCA, and demultiplexes the received signals for each stream from signals in an identical OAM mode.
