This paper has proved that the existing TD-SCDMA smart antenna system can be used only for baseband waveform pre-equalization,with no basic functions needed for smart antenna system at all such as DOA(direction of atenna) detection,beamforming,and space division multiple access.It will lead to a special system whose uplink capacity is larger than the downlink one.Unable to meet the basic requirements of 3G mobile communication system.This paper proposes a basic method which can realize the DOA detection and beamforming in the TD-SCDMA syetem to provide the capability of space division multiple access.The ratio of performance over cost of TD-SCDMA system can be greatly improved
