Performance analysis for multimedia CDMA networks under the received power minimization model

Performance analysis for multimedia code division multiple access (CDMA) networks under the received power minimization model is addressed in this paper. The received power minimization model considering intercell interference is formulated as a constrained optimization problem, based on which the system admission region is also defined. The handoff prioritized call admission scheme is then described and evaluated using the K-dimensional birth-death process model. A more general assumption that average channel holding times for new calls and handoff calls are not equal and an effective approximate model are adopted in the performance analysis. Numerical examples are given to demonstrate the system performance in terms of blocking probabilities and resource utilization. It is shown that the system performance meets the design objectives.
