| Abstract: |
| Smart antenna and spatial diversity receiving are two most important spatial signal processing technologies.In this paper the radio propagation characteristics of the transmission path, spatio-temporal channel model and channel characteristics in different environments are studied. On the basis of those analysis, the operating principle of smart antenna and spatial technology is analyzed with focus on the differences between the two technologies in several aspects. |
| Key words: Mobile communication,Spatial signal processing,Smart antenna,Spatial diversity receiving technology |
