SIR-based call admission control by more realistic imperfect power control for CDMA system

This paper proposed a more realistic imperfect power control model for Signal-to-interference radio (SIR)-based call admission control algorithms comparing with the previous method in CDMA systems. A new call is accepted by a base station if the measured SIR can be guaranteed based on our proposed model. Similarly, we considering the voice, data multimedia traffic services, etc. The simulation results show that the proposed model used in the same CAC scheme outperforms the previous model used in the same schemes.
