Abstract
In this thesis, the advantages ot TD-SCDMA compared to WCDMA were given. It starts with the background introduction of third generation system development. Followed by WCDMA radio access network description, the TD-SCDMA developing background will be given. Physical Iayer and the key technologies used in TDSCDMA take the most part of the thesis. Finally the advantages for using TD-SCDMA compared to WCDMA are given at the end of the thesis. The research is based on the Release 4 standards in 3GPP. The research of TD-SCDMA advantage was focused on two aspects, technology and commercial. The research result shows a significant improve for spectrum efficiency. The Iow frequency band operation could reduce the cost of BTS. The overall cost efficiency will be improved by using TD-SCDMA compared to WCDMA system. Since TD-SCDMA system has not been used for commercial, this thesis work has been done based on the theory studies.
