| Abstract: | The capacity improvement mechanism with beam-tilting antennas for multi-cell base stations was studied under the consideration of the effect of log-normal shadowing, the height of antenna and the beam width. A beam-tilting scheme for multi-cell base stations of the CDMA cell system was proposed, in which beam-tilting technology for base stations is used in the whole CDMA cell system. The simulation results show that with the new scheme, the system capacity can be greatly improved. |
