Abstract :
We propose a theoretical method in order to estimate the forward link outage probability and user capacity of a cellular system which are based on IS-95 CDMA standard - especially the impact of a power control strategy and voice activity monitoring on the system under long-term fading. According to the numerical results obtained the power control strategy leads to approximately threefold the user capacity compared to the situation without power control. The power control strategy not only improves the desired signal to interference ratio in the reference user´s receiver, but also offers uniform service to the user wherever it is located in the cell.
