| Abstract: | The effective capacity region of the two-user opportunistic spectrum access (OSA) system in Rayleigh fading environment is derived in this paper.Although OSA is a contemporary research topic,little attention has been given to the capacity analysis under quality-of-service (QoS) constraints.Hence,we use the effective capacity,which is a powerful tool to analyze the QoS requirements in wireless communication systems,to study the sustainable packet arrival rate of the secondary users while meeting statistical ... |
