The Study And Realization Of Controlling System About TD-SCDMA Repeaters

The mature of TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) technology for the third-generation mobile communications (referred to as 3G) system and the issuance of 3G licenses mark the TD-SCDMA system will be widely used in China. Like other wireless networks, the TD-SCDMA system will also produce the result that the signal is faint or vacant in some areas.So wide applications of TD-SCDMA repeaters will be necessary. With more and more repeaters increasing, it is important to build the Controlling System of TD-SCDMA Repeaters to manage them.The design and realization of Controlling System about TD-SCDMA speaker are given in this paper. At first the paper introduces the TD-SCDMA system and its key technologies such as Smart Antenna,Joint Detection,and then it gives a brief outline about repeaters, including the technologies, applications,the method for the synchronization, the function of the Controlling System and total design etc... The forth chapter introduces the working principle about the hardware of Controlling System,and describes the realization of all parts of the circuit.The fifth chapters mainly introduces the disgn and realization of the softerware about the Controlling System. AT last,it summarizes the course of the study about the whole controlling system.
