Abstract

In CDMA (code-division multiple-access) systems, the reverse link power control is used to reduce the near-in to far-out interference generated by the mobile units in different locations within a cell. The signal of a near-in mobile unit will interface with that of a far-out unit at the cell site if no power control scheme is used. The forward link power control is used to increase capacity. It is needed to take care of both near-in and far-out units. Therefore, a scheme which will increase capacity by an additional 1.8 times compared to no-power control on the forward link is proposed
