| Abstract: |
| In information age, the demand for communication service increases constantly. So higher requirement for the communication technology is raised. The Spatial-Division-Multiple-Acesse (SDMA) technology calls attention broadly by its unique advantage of increasing system capacity and frequency spectrum utilization. In this paper the authors discuss thoroughly SDMA technology from such aspects as basic concept,channel model,realization and improvement of the performance of communication system. |
