| Abstract | ||
| Abstract In this paper soft handover parameters in WCDMA system are investigated. They include the effect of imperfect power control on the downlink capacity and power assignment to the mobile station, the micro diversity gain which represents the gain in the downlink direction, and the macro diversity gain which represents the gain in the uplink direction. The results showed that the power control error increases the total power consumption by the mobile station which leads to decrease the capacity (number of users per cell). Soft handover decreases the fade margin which leads to improve the coverage area. During soft handover the mobile station needs lower signal to noise ratio compared with no soft handover to obtain the specific bit error rate.
