Since there is an infinite increase in number of users in a cellular radio system, limited resources must be efficiently used. Hence, closed-loop power control is important in resource planning. For DS-CDMA systems, there are different users transmitting signals to base stations, from various distances with difference power. In the DS-CDMA power control system architecture, round-trip delay, channel fading and noise. According to the SINR signal (Signal-to-Interference-plus-Noise-Ratio) feedback, design the controller to control the limited power between the base station and transmitter station and make the system to the stable. The other part of our research time-varying delay. In order to achieve the target power we use the CMAC.
