This paper tells of the space-time coding technology. And by utilizing the especial frame structure of TD-SCDMA system, two schemes in combination of space-time coding technology and the TD-SCDMA system are proposed. In the transmission side, the data based on data field of a burst is encoded, while in the receiver side, is received and the data through one or two antenna and the two data fields decoded simultaneously. Due to the adoption of transmit diversity technology, the simulation results prove that it can remarkably improve the performance of TD-SCDMA system.
