Abstract
Connection admission control (CAC) for wireless multi-code CDMA (MC-CDMA) systems supporting multi-rate services is investigated under perfect and imperfect power control, respectively. The CAC scheme guarantees that the required quality-of-service (QoS) performance can be satisfied during the entire lifetime of a connection once it is admitted. Connection level grade of service (GOS), in terms of connection blocking probability (CBP) and resource utilization, is derived. Simulation results show that: (1) Compared with perfect power control, imperfect power control increases the required level of received power in order to achieve the same QoS and reduces the system resource utilization; (2) The proposed CAC scheme is more desirable when the required resources among the traffic classes are significantly different.
