Abstract:   Network Coverage and Capacity is an important objective, when characterizing the performance of high-data-rate services. The use of soft-handoff may have an impact on the downlink of cellular CDMA systems. The capacity of the mobile is commonly limited by interference. In order to reduce the interference level in downlink, power control techniques are proposed in the system. The power control techniques are used to reduce the system interferences in the downlink.The purpose of this thesis is to give an overview on power control in CDMA cellular systems. It gives general definition of handoff, power control, objectives, and its employment in forward links.
