| Abstract: | Based on the theory of noise-limitation and on actually surveys of capacity on a cell and as well started research with soft-capacity of CDMA mobile system,algorithms is proposed for computing wireless capacity of CDMA 2000 mobile system in 3G.Several primary factors that affect capacity on uplink and downlink are separately discussed,and the formulas for capacity on uplink and downlink are obtained.The interference between the cell and adjacent cells are analyzed and simulated.The relationships among several important variables are also verified. |
