Abstract
Adaptive power control has widely been used in DS/CDMA systems to overcome the so-called “near-far” problem. This chapter studies the adaptive open-loop power control of a cellular CDMA system, which is overlaid in downlink by a narrowband signal. The effects of downlink power allocation schemes to power control error in the presence of narrowband interference are analyzed and numerically computed. In order to get a minimum power control error in the CDMA overlay situations, an optimum downlink power allocation scheme is used, which works well for wide range of signal to narrowband interference ratio.
