“…In the proposed MG-MIMO [22], the PSOAM MG antennas are merely applied to the transmitting end, the receiving end still use the common antenna like the standard horn antenna to form an ULA. The proposed architecture takes advantage of the phase diversity of the MG rather than the orthogonality just like most of the OAM MDM systems do.…”

Spatial division multiplexing using conventional orbital angular momentum (OAM) has become a well-known physical layer transmission method over the past decade. The mode-group (MG) superposed by specific single mode plane spiral OAM (PSOAM) waves has been proved to be a flexible beamforming method to achieve the azimuthal pattern diversity, which inherits the spiral phase distribution of conventional OAM wave. Thus, it possesses both the beam directionality and vorticity. In this paper, it's the first time to show and verify novel PSOAM MG based multiple-in-multiple-out (MIMO) communication link (MG-MIMO) experimentally in a line-ofsight (LoS) scenario. A compact multi-mode PSOAM antenna is demonstrated experimentally to generate multiple independent controllable PSOAM waves, which can be used for constructing MGs. After several proof-of-principle tests, it has been verified that the beam directionality gain of MG can improve the receiving signal-to-noise (SNR) level in an actual system, meanwhile, the vorticity can provide another degree of freedom (DoF) to reduce the spatial correlation of MIMO system. Furthermore, a tentative long-distance transmission experiment operated at 10.2 GHz has been performed successfully at a distance of 50 m with a singleway spectrum efficiency of 3.7 bits/s/Hz/stream. The proposed MG-MIMO may have potential in the long-distance LoS backhaul scenario.

Structure radio beams with diverse radiation patterns exhibit huge potentials in many applications. In this paper, we propose a plane spiral orbital angular momentum (PS-OAM) based structure radio beam construction scheme, in which several PS-OAM waves are superposed together to acquire the anticipated radiation pattern and phase distribution in azimuthal domain. Firstly, some typical shapes of the radiation patterns are demonstrated. Then, the properties of this kind of structure radio beam, for example diversity, periodicity, vorticity and directional gain are analysed in detail from mathematical analysis and simulation verification. Finally, a proof of principle experiment is carried out at 10 GHz using a multi PS-OAM antenna to further testify the feasibility of the structure radio beam construction. The interesting properties provided by structure radio beams would offer promising solutions to radar imaging, smart antenna, massive multiple input multiple output (MIMO) and spatial modulation multiple input multiple output (SM-MIMO).

“…The prospects of OAM mode-groups(MGs) in MIMO system, low interception communication system, and spatial field digital modulation system [84] have been explored. [85] proposed a plane spiral OAM (PSOAM) MG based MIMO communication system, which regarded PSOAM MG as an independent transmitting antenna. The simulated results showed that the scheme could increase the channel capacity, which meant that PSOAM MGs could not only improve the signal-to-noise ratio (SNR) of system but also decreased the spatial correlation of sub-channels.…”

It becomes more and more challenging to satisfy the long-term demand of transmission capacity in wireless networks if we limit our research within the frame of traditional electromagnetic wave characteristics (e.g., frequency, amplitude, phase and polarization). The potential of orbital angular momentum (OAM) for unleashing new capacity in the severely congested spectrum of commercial communication systems is generating great interest in wireless communication field. The OAM vortex wave/beam has different topological charges, which are orthogonal to each other. It provides a new way for multiplexing in wireless communications. Electromagnetic wave or synthetic beam carrying OAM has a spiral wavefront phase structure, which may provide a new degree of freedom or better orthogonality in spatial domain. In this paper, we introduce the fundamental theory of OAM. Then, OAM generation and reception methods are equally demonstrated. Furthermore, we present the latest development of OAM in wireless communication. We further discuss the controversial topic "whether OAM provides a new degree of freedom" and illustrate our views on the relationship between OAM and MIMO. Finally, we suggest some open research directions of OAM.
