Abstract
We study the effect of Interference Cancellation (IC) on the Call Blocking Probabilities (CBP), in the uplink of W‐CDMA networks supporting multiple service‐classes with finite number of traffic sources. We propose an approximate but recurrent formula for the calculation of the system state probabilities and CBP that captures the IC efficiency parameter, as well as other parameters peculiar to W‐CDMA networks such as soft blocking and user activity. To this end, we describe the state transition diagram of the W‐CDMA system by one‐dimensional Markov chain. The analytical CBP results are compared with simulation results in order to verify the validity of the proposed formulas and reveal their accuracy. In addition, we show the consistency of our analysis when the number of traffic sources becomes infinite. Copyright © 2010 John Wiley & Sons, Ltd.
