Abstract :
The effects of imperfect power control and soft handoff on the capacity of DS-CDMA cellular systems are investigated. In our analysis, the approach is to employ appropriate models for signals and network configuration and derive analytical results. For power control error, the received signals at the cell site are modeled differently and the fitness of models are argued. In the other part, soft handoff effect in reducing forward-link capacity is studied based on a simplified cell model. The result of this study questions the improvement of system capacity due to soft handoff
