Abstract

Abstract

Focusing on the problem that the free space propagation model could only describe the propagation characteristics of vortex channel carrying Orbital Angular Momentum (OAM) in free space scenario, and the deterministic sparse multipath vortex channel model is strictly dependent on the propagation environment and could not accurately describe the propagation characteristics of OAM channel in real multipath scenario, a statistical modeling method for millimeter wave OAM multipath channel is proposed in this paper. In indoor corridor environment, Uniform Circular Array (UCA)-based OAM radiation transmission system is constructed, and the OAM multipath channel model is established based on optical ray theory and UCA radiation characteristics. Results show that the wavefront phase and amplitude of OAM channel in indoor corridor multipath environment can be accurately characterized by uniform distribution and Nakagami-m distribution in millimeter bands. The channel amplitude follows Rayleigh distribution when the propagation distance is large under the Line-of-Sight (LoS) and Non-LoS (NLoS) propagation conditions, and that follows Rician distribution when the propagation distance is small under the LoS propagation conditions.
