Abstract

A time scheduling scheme satisfying both the detection performance of a cognitive node in cognitive networks and the QoS requirement of a secondary user under fading channels is proposed in this paper. First, an optimal sensing time is obtained by maximizing the achievable throughput of a secondary user under the constraint that the primary user is sufficiently protected. Then, according to the second order statistic characteristics of fading channels, the transmission time is defined under the outage capacity constraint of a secondary user. Finally, a secondary sensing time is defined for the necessary of both primary protection and the guarantee of transmission QoS. It turns out to be an efficient scheme of spectrum utilization and time scheduling.
