Smart antenna technology is the representation of the third generation mobile communication

TD-SCDMA standard has the largest distinction and advantage compared with others

which has the advantages of increasing system capacity

expanding the system coverage

improving the quality of service

and so on. With the commercial using of TD-SCDMA network

smart antenna technology is gradually mature. In this paper

I will talk about some knowledge and advantages of TD-SCDMA mobile terminal smart antenna technology

and to achieve the adaptive algorithm by DSP and FPGA.
