Abstract
A beam domain channel modeling method for an orbital angular momentum wireless communication includes 1) establishing a geometry-based stochastic model and considering a near-field effect and a mutual coupling; 2) deriving a beam sampling matrix by utilizing a beamforming matrix, and establishing a beam domain channel model under a spatial multiplexing; and 3) implementing a simulation channel model based on a channel transfer function, and deriving and analyzing channel statistical properties. The beam domain channel model for the orbital angular momentum wireless communication established in the present disclosure is an extension of the channel models based on the plane wave, which considers the near-field effect and the mutual coupling, supports the spatial multiplexing, enriches the modeling methods for the orbital angular momentum channel in the non-line-of-sight scenarios, and is reduced in computation complexity compared with the geometry-based stochastic model.
