Orbital Angular Momentum Radio: A new possibility for Full Duplex Radio?

Recently Orbital Angular Momentum Radio (OAM-Radio) has been shown to provide huge gains in spectral efficiency for line-of-sight radio links. This has been achieved by means of either using antenna arrays and signal coding (akin to MIMO) or circular phase plates to provide the required signal profile. It may also be possible to use this concept towards enabling full-duplex radio by using the filtering function at the OAM-radio receiver. This talk introduces and reviews recent work on OAM-radio and then explores the possibility of applying it in the context of full-duplex radio.
