ABSTRACT
The most important aspect in WCDMA is power control without it a single overpowered mobile could block a whole cell which is called near – far problem .WCDMA power control techniques are open loop power control and closed loop power, WCDMA power control with rate 1500 Hz is supported in both uplink and down link, this high rate of power control is estimated and adjusted to face the fast variations in the location of the mobile in the network. In this Thesis different power control rates are proposed by decreasing the number of power control bits in WCDMA frame. A simulation is used to study the effect of the power control bits reduction in increasing the system capacity. The calculations are carried out to various data rates and various time instances to calculate the number of users which it used to evaluate
The power control at different rates
