Abstract

Abstract

The Orbital Angular Momentum (OAM) satisfies orthogonality between each mode, which provides a new multiplexing dimension for wireless communication systems. At present, OAM communication still focuses on the Line of Sight (LoS) scenarios. The OAM Multiple Input Multiple Output (OAM-MIMO) communication system performance can be deteriorated by the non-ideal transmission conditions such as multipath and misalignment effects in the real scenarios. In order to improve the performance of the OAM-MIMO communication system, a millimeter-wave OAM-MIMO ten-rays channel in the actual transmission scenario is modelled in this paper; Then, the performance loss caused by multipath and misalignment effects are evaluated; Finally, a low-complexity Average Phase Compensation and Iterative Power Allocation (APC-IPA) joint optimization scheme is proposed to eliminate the phase deviation from the misalignment and multipath effects, and improve the capacity. The simulation results show that the proposed APC-IPA joint scheme increase effectively the channel capacity of the system when suffering from misalignment and multipath effects.
