Statistical channel modelling of full-angle 3.5 GHz OAM in indoor corridor scenario

A 3.5 GHz OAM antenna with +/- 1 mode was designed and fabricated, and the channel measurement in frequency domain was used to measure the channel in full angle domain under indoor multipath scenarios. Then, the modified probability density function of Gaussian distribution, Laplacian distribution, and Von Mises distribution are used to establish the OAM full-angle statistical channel model. The fitting curve results well represent the statistical characteristics of OAM in indoor multipath scenario.
