Studies And Simulations On Smart Antenna In TD-SCDMA System

Now more and more communication equipment manufacturers pay attention to TD-SCDMA that was lodged by CWTS, because TDD and SA are applied in TD-SCDMA. TD-SCDMA,WCDMA and CDMA2000 have been the most popular standards of 3G.After introduced the development of Mobile Communication, we detailed introduce SA and TD-SCDMA in this thesis. We complete the simulation of the TD-SCDMA uplink and compare the performance of TD-SCDMA that applied SA with the performance of TD-SCDMA that didn't apply SA. The simulation result indicates that we can improve the TD-SCDMA performance with SA.We research and simulate the BeamForm algorithms of SA. After we compared the performances of the BeamForm algorithms, an advanced BeamForm algorithm is lodged. The calculations of the BeamForm algorithms are lightened with this advanced BeamForm algorithm.We research and simulate the DOA algorithms of SA also. we compared the performances of the DOA algorithms through the simulation.In the end, we lodge that ACS was applied in TD-SCDMA, and we give the system design scheme. It is proved through the simulation that we can improve the TD-SCDMA performance with ACS.
