چکیده
| We analyze a slotted DSCDMA system to guarantee QoS requirements for realtime tra c [1]. A Markovian analysis for realtime tra c and an equilibrium point analysis (EPA) for non-realtime tra c are applied in a heterogeneous environment. Packet losses for realtime tra c, delay times for non-realtime tra c, and wireless link utilization are derived.

متن کاملAdmission control for variable spreading gain CDMA wireless packet networks
A technique for variable spreading gain code-division multiple access (VSG-CDMA) with transmit power control has recently been proposed [4], [5] to provide integrated services in a wireless packet network. System capacities of VSG-CDMA networks with and without considering user activity factors were derived. The analysis gives a lower bound of system capacity because a user’s transmitted power ...
