Instantaneous and local-mean power control for direct-sequence CDMA cellular networks

Proposed and existing power-control systems for directsequence CDMA cellular networks measure instantaneous power, whereas theoretical analyses almost always assume long-term-average or local-mean power control. In this paper, the distinction between the two types of power control is clarified. The outage probability for direct-sequence CDMA systems using instantaneous power control is derived. The results of the analysis of local-mean power control are shown to be similar to those provided by a far more elaborate theoretical analysis.
