Wcdma Base Station (nodeb,) Self-loop System The Rnc / Cn Analog Module Design And Development

With the Developent of mobile communication systems, the Third generation systems are under the way0 It can provide the high bit rate servies that enable high quality images and vidio to be transmitted and receiced,and to provide access to the web with high data rates. It can provide whatever kind of communication any time and any where.All of the interface in WCDMA use the common protocol modal and the principle is partition the system with plans and layers. The benefit of the idea is patent,for example, the change about any layer will not affect the other layer.That is to say the idea benefit for the upgrade any layer of the whole system.Nodeb and RNC is important parts of the WCDMA sub-system, the interface between them is called lub. This thesis is design a module to simulate the protocol frame of the lub and fulfill the NBAP signal and the RRC management function of the RNC. This can make it possible that UE circulate the data from NodeB without RNC.
