Firstly a downlink transmission model which includes smart antennas is developed. Based on this model, the TD-SCDMA downlink transmission beamforming methods, in consideration of a mobile terminal using various data detection algorithms (joint detection, single detection), are discussed respectively. Three beamforming methods have been evaluated and two of them have been modified in order to make them available for the TD-SCDMA systems. Furthermore, the data detection methods have been investigated under the influence of these beamforming methods.
