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...
A novel WCDMA network structure using ad hoc relaying is proposed in the paper. With the aid of ad hoc relaying, we consider that all the mobile stations in WCDMA system are dual-mode, having both ad hoc and WCDMA functions. This makes the terminals more convenient for personal communication. In this paper, the conventional mobile cell is divided into three areas: heavy interference area, voice area...
