A Queueing Model of a Spread Spectrum Multiple Access

Abstract
We propose a queueing model of the reverse link from mobiles to the base station in a single cell of a cellular DS-CDMA system. Approximation of independent queues leads to a non-linear fixed point equation that describes globally or locally stable system modes. We argue that interactions between queues at different mobiles through interference at the base station are essential for the system queueing performance including traffic delays and backlogs. To account for these interactions we propose to model DS-CDMA by the enhanced Generalized Processor Sharing (GPS) scheduling discipline. It appears that this model strikes a compromise between accuracy and tractability. At least some already known performance results for GPS can be directly used or adjusted to provide performance estimates for DS-CDMA.Proceedings Title
