Abstract:

A novel multiuser transmission (MUT) model is developed. In this model, the smart antennas method is combined the multiuser transmission. The smart antennas are used to eliminate the space interference and the MUT is used to mitigate the multiple-access interference (MAI) and the inter-symbol interference (ISI). The simulation in the time division–synchronous code division multiple access（TD-SCDMA） system shows that the proposed system model can achieve a better performance than the model which only uses MUT method in the spatial domain environment.

Key words: time division-synchronous code division multiple access, smart antennas , multiuser transmission, channel estimation
