摘要

In this paper, analysis is advanced by computer simulation for the purpose of an improvement of 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 capacity. By changing cell-size, the result says that capacity can be improved about 140 users especially in a Center-Focused distribution. Also in the Edge-Focused distribution, capacity, about 60 users, is improved. 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.
