Abstract :
The key obstacle to exploiting orbital angular momentum in wireless communication is the influence of axis misalignment on detection side. This paper summarizes the effects of axis misalignment quantitatively and presents novel automatic methods to overcome the obstacle under the ideal (noiseless) condition. Numerical results in the far field demonstrate the effectiveness of our approach to make orbital angular momentum in wireless communication feasible and reliable.
