This paper addresses the call admission control problem for multiservice wireless code division multiple access (CDMA) cellular systems when the physical layer channel and receiver structure at the base station are taken into account. The call admission problem is formulated as a semi-Markov decision process with constraints on the blocking probabilities and signal-to-interference ratio (SIR). By using recent results in large random matrices, the SIR constraints incorporate linear multiuser detectors and fading channels. We show that the optimal call admission policy can be computed via a linear programming-based algorithm.
