Abstract
A system for providing full-duplex communications includes a first transceiver for transmitting first signals having a first orthogonal function of a plurality of orthogonal functions applied thereto on a first channel and receiving second signals having a second orthogonal function of the plurality of orthogonal functions on a second channel at a same time. A second transceiver transmits the second signals having the second orthogonal function of the plurality of orthogonal functions on the second channel and receives the first signals having the first orthogonal function of the plurality of orthogonal functions on the first channel at the same time. The first channel having the first orthogonal function applied thereto and the second channel having the second orthogonal function applied thereto do not interfere with each other enabling full duplex transmissions between the first transceiver and the second transceiver.
