摘要

In this paper, analysis is advanced by computer simulation for the purpose of an improvement of the capacity in W-CDMA. A situation in which there is some deviation on the user's distribution in the center cell, and the relation between cell size and capacity is evaluated. It is important to improve the capacity not only the reference cell but also the surrounding cells, when evaluating the capacity. By changing the cell-size, the result shows that the capacity can be improved by about 140 users especially in a center-focused distribution. Also, in the edge-focused distribution, the capacity can be improved by about 60 users. In addition, it is connected with the increase in the capacity by changing the cell-size even in the other user's distribution. The capacity increased by the effect of soft handoff. The larger the threshold was, the more the reverse link capacity increased. It is shown that the reverse link capacity is converged when threshold is about 6 dB.
