Since interference is related to the capacity and performance of DS/CDMA systems, it is necessary to investigate other-cell-interference characteristics according to the location of a user. The ratio of the intercell interference to the total power received from the user's own cell in a downlink, defined as the other-cell-interference factor, as a function of normalised distance is specifically analysed. Additionally, the maximum transmission rate under uniform user distribution throughout the cell is simulated when TDX mode packet scheduling is applied. The results show that a maximum transmission rate up to 7.6 Mbit/s for the privileged user could be supported under the following conditions: when the bandwidth is 1.2288 MHz, the orthogonality factor is 0.9, the path loss is 4 and the normalised distance is 0.1.
