Abstract :
In this paper, the effects of imperfect power control on the reverse link outage probabilities of cellular CDMA systems employing successive interference cancellations (SIC) are thoroughly investigated. Both theoretical and computer simulation results show that the capacity of cellular CDMA systems employing SIC are very sensitive to imperfect power control. Hence, this is a large capacity gap between the systems following current power control standards and those with perfect power control. By tightening power control standards with new technologies, the capacity of cellular CDMA system employing SIC can be improved significantly.
