摘要

Smart antenna technology is a key technology adopted in TD-SCDMA communication system. There are two main functions of smart antenna, including DOA estimation and beamforming. It is usually difficult to implement the function of smart antenna directly in TD-SCDMA system simulation in OPNET, which is a network simulation tool suited for system level simulation. In this paper, two simulation methods by integrating OPNET with MATLAB are surveyed. Then the uplink and downlink beamforming processes of smart antenna in TD-SCDMA system are implemented during system level simulation with these two methods respectively. An example is also given to verify the function of smart antenna by implementing uplink and downlink beamforming in the system level simulation. Simulation results show the performance improvement caused by smart antenna in the whole system.
