| Abstract: | An approach to determine the uplink capacity and load of code division multiple access((CDMA)) systems employing the smart antenna technique was presented.The impacts of average antenna interference gain,inter-intra interference ratio,and multi-user detection factor were determined.By simulation,the analytical approach and the deduced expressions are demonstrated to be well available in the uplink capacity planning and the optimization of advanced radio resource management schemes. |

| Keywords: | code division multiple access smart antenna uplink capacity background noise rise |
