Application of orbital angular momentum to Fiber, FSO and RF
A communications system includes transmitter circuit for receiving a plurality of input data streams and applying a different orthogonal function to each of the plurality of input data streams. The transmitter circuit processes each of the plurality of input data streams having the different orthogonal function applied thereto to spatially locate a first group of the plurality of input data streams having the different orthogonal function applied thereto onto a first carrier signal and to spatially locate a second group of the plurality of input data streams having the different orthogonal function applied thereto onto a second carrier signal. The transmitter circuit temporally locates the first carrier signal and the second carrier signal onto a third carrier signal and transmits the third carrier signal over a communications link. A receiver circuit receives the third carrier signal over the communications link and separates in time the third carrier signal into the first carrier signal and the second carrier signal. The receiver then separates the plurality of input data streams having the different orthogonal function applied thereto into the plurality of input data streams each having the different orthogonal function applied thereto. Finally, the receiver removes the orthogonal function from each of the plurality of input data streams and outputs the plurality of input data streams.
