A HAPS-CDMA Call Control Solution Based on Platform Swinging Model
Sun Song-lin · 2011
The effects of the platform swinging on HASP-CDMA system are analyzed to complete the study on the HAPS instability,the intercell and intracell interference factors caused by the platform swinging are defined,and the capacity algorithm of the HAPS-CDMA swinging model is given.Then a novel user access solution is presented,namely the mechanisms of the signals from the users in the edge of the center reference cell in the swinging direction received by both of the two adjacent base stations to avoid the pingpong handover.From numerical results it is observed that the algorithms can balance the system capacity and the resource well,and improve the system performance significantly.
