This paper presents a comprehensive review of the published algorithms on
power control for cellular systems. The majority of the research is focused on
Code Division Multiple Access (CDMA) systems, although a small fraction of
the reviewed literature pertains to Frequency Division Multiple Access (FDMA)
and Time Division Multiple Access (TDMA).
Power control in cellular systems is applied to numerous communication archi-
tectures. For Frequency Division Multiple Access (FDMA) and Time Division
Multiple Access (TDMA) power control reduces intercell interference and im-
For Code Division Multiple Access (CDMA) power control is a required part
of the base station and mobile station designs. Power Control reduces interfer-
ence due to multiple users in the same frequency band. A general term that
characterizes this type of multiple access interference is the "near-far effect".
