| Abstract: | Smart antenna and joint detection technology ,which have been adopted as the key technology in 3G system,are combined together first time in TD-SCDMA system. This paper analyse the possible influences for the performance of TD-SCDMA network base on the smart antenna and joint detection technology in the aspect of interference analysis, make a conclusion of TD-SCDMA system's characteristic of code-limited, and put forward the primary suggestion of chip plan. |
