Abstract
In this letter, the authors analyze the stability and throughput of a cognitive wireless communication system with cognitive link using same antennas structure as primary link. With the assumption that a possibility of detection error pe will occur due to misty and indetermination of wireless channels, the cognitive link and primary link are interacting queue system in real circumstance. We do stability analysis of an equivalent dominant system to case of interaction queues with Loynes' stability criteria. Based on the studies, we derive throughput and optimal power allocation schemes for two links. The proposed mathematical analysis is complemented by various performance evaluation results, which demonstrates the accuracy of the theoretical approach.

On ergodic sum capacity of fading cognitive multiple-access and broadcast channels
This paper studies the information-theoretic limits of a secondary or cognitive radio (CR) network under spectrum sharing with an existing primary radio network. In particular, the fading cognitive multiple-access channel (C-MAC) is first studied, where ...
Optimal power allocation for fading channels in cognitive radio networks: ergodic capacity and outage capacity
A cognitive radio network (CRN) is formed by either allowing the secondary users (SUs) in a secondary communication network (SCN) to opportunistically operate in the frequency bands originally allocated to a primary communication network (PCN) or by ...
Improving spectrum access using a beam‐forming relay scheme for cognitive radio transmissions
Cognitive radio (CR) systems allow unlicensed secondary users to transmit on the licensed frequency bands without degrading the transmissions of licensed primary users. Combining CR with other emerging techniques such as multi‐antenna relaying may bring ...
