摘要

In this paper, we analyze the forward-link capacity of a cellular DS-CDMA system, especially the effects of power control, path loss exponent (/spl gamma/) and orthogonality factor (f/sub 0/) of multipath propagation on the system. The problem of finding an optimum power control factor (n) is evaluated. According to n, the proper threshold distance is estimated for optimum performance. With these factors, the numerical results show that the capacity is reduced by changing f/sub 0/ from 0.7 to 0.2 and /spl gamma/ from 5 to 3.
