- Abstract:
-
In order to improve the speclral efficieney of delay sensitivity of channel, we present a novel frame-work of changing the transmission parameters aeeording to the dynamie aecess mode. Based on the underlay-interweave hybrid aeeess mode, this framework is modeled as a optimization problem in which the primary andsecondary users adjust transmission parameters with the constraints of the elfeetive speetral elficieney of theprimary link, the average transmission power of the cognitive link, dual quality-of-serviee (00S)measures,namely, average packet error rates and time delay, constraints of both links, to maximize the elfeetive speelralelicieney of the cognilive user. The numerical results show that a better tradeolf ean be achieved between theproteelion of primary user and the elfeelive speelral elfieieney of cognitive system when the delay is introdueedand the constraint is salisfied.
