Abstract :
This paper considers the effect of unequal power control in direct sequence CDMA cellular networks in the reverse direction to achieve differentiated quality of service. In particular, power control can be used to maintain the required Eb/I0 for a given type of traffic to meet the desired service quality. Here, an analytical approach is used to determine the probability of outage when two types of traffic with different quality of service requirements coexist. Results are presented for systems with equal and unequal power control
