Stable Throughput Region of Cognitive-Relay Networks with Imperfect Sensing and Finite Relaying Buffer

摘要

In this letter, we obtain the stable throughput region for a cognitiverelaying scheme with a finite relaying buffer and imperfect sensing. Theanalysis investigates the effect of the secondary user's finite relayingcapabilities under different scenarios of primary, secondary and relaying linksoutages. Furthermore, we demonstrate the effect of miss detection and falsealarm probabilities on the achievable throughput for the primary and secondaryusers.
