In this paper, we mathematically analyze stable throughput for an interweave cognitive radio system employing Selective Repeat-Automatic Repeat Request (SR-ARQ) protocol. We model the cognitive link and primary link as interacting queue systems and perform stability analysis of an equivalent dominant system for the case of interacting queues with Loynes’ stability criteria. Based on the studies, we derive optimal power allocation schemes for two links.
