This paper aims at balancing the load of OFDMA small cell networks. Different with the existing works that define the load as the number of service user equipments or the occupied amount of resources, we model the load as the service ability of small cells. The system load balancing problem that adopts the max-min fairness measure is formulated as a(More)
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(More)
