A Study On TD-SCDMA Network Optimization In Incipient Network Construction Of Suqian Mobile

TD-SCDMA is a time division duplex (TDD) Code Division Multiple Access (CDMA) system, on the contrary, WCDMA and CDMA2000system use frequency division duplex (FDD) technology. TD-SCDMA has a unique place on the optimization of the wireless network. The main purpose of incipient optimization of TD-SCDMA network construction is to achieve the goals of network planning, find the problems of network coverage, quality of service, etc., summarize the experience in network optimization to ensure ongoing network optimization, and constantly improve the quality of the network and optimization level, so as to ensure the quality of the network construction.In the first place, this thesis introduces the background of subject study, and analyzes the TD-SCDMA network indicator and current quality situation. Then, it researches the network characteristics which include the technology of TDD, smart antenna, united detection, uplink synchronization, baton handover, dynamic channel allocation, etc, and does some research on the shortcomings of TD-SCDMA network too. In the end, illustrated with the incipient construction optimazation in Suqian Mobile, with analyzation of some problems on coverage of network, quality of service etc, the measurements of network optimazation are discussed, the experiences of network optimization are sumed up, the methods of network quality improval are proposed. The opimization schemes proposed in this thesis are proved to be feasible by practice.
