Analysis of imperfect power control in CDMA cellular systems

An analytical model is presented to study the effect of power control error in a CDMA cellular system. The forward link capacity and reverse link capacity are evaluated for perfect and imperfect power control cases. In our model, two forward link power control (nth-power-of-distance power control and optimum power control) and one reverse link power control schemes are examined. The effect of the dynamic range of transmission, moreover, has also been analyzed.
