Abstract
There is no theoretical time or frequency restrictions on capacity in DS-CDMA systems. In these systems, the signal to interference ratio (SIR) has a major effect on capacity. Since an increase in the user SIR at the base station (BS) leads to higher capacity, transmission power control is employed. The nonuniform distribution of users in the network causes different quality of service (QOS) in distinct regions, therefore network resources may not be utilized properly. A dynamic distribution algorithm can be employed to balance the QOS delivered in different regions of the network. In this paper, a novel dynamic distribution algorithm is introduced. The proposed algorithm deactivates certain users when the network encounters an overload. By applying this policy, the required SIR can be maintained for the remaining users.
