Abstract

Smart antenna technology is one of key technologies used in the TD-SCDMA system. By using DSP algorithms and dynamically generating the beam patterns, a smart antenna can greatly reduce the interference and increase the system capacity. The concept of smart antenna is presented and a novel detection technique called joint space-time processing based on the smart antenna is described. Simulation results on the uplink performance of TD-SCDMA in a macrocellular environment are also included. It can be seen that the smart antenna system has much better performance than a system without a smart antenna and can meet the requirements of the third-generation systems
