Abstract
A system for providing full-duplex communications comprises a first transceiver for simultaneously transmitting first signals having a first orthogonal function applied thereto on a first channel and simultaneously receiving second signals having a second orthogonal function applied thereto at a same time. A second transceiver simultaneously receives the first signals having the first orthogonal function applied thereto on the first channel and simultaneously transmits the second signals having the second orthogonal function applied thereto at the same time. Application of the first orthogonal function to the first signals and application of the second orthogonal function to the second signals prevents interference between the first signals and the second signals.
