We develop a general model to study the forward-link capacity of a code-division multiple access (CDMA) cellular system with power control. Using this model, two forward-link power control schemes (nth-power-of-distance power control scheme and optimum power control scheme) are examined. The increase in capacity by using power control has been studied. The capacities of the forward link are also compared with those of the reverse link with perfect power control. In the case of imperfect power control, an analytical model is presented to study the effect of power control error in a CDMA cellular system. The effect of the dynamic range of transmission, moreover, has also been analyzed
