Spectrum handoff based on adaptive weights adjustment

Spectrum handoff is one of key technologies of cognitive radio. A spectrum handoff strategy based on adaptive weights adjustment is proposed, considering the effect of secondary users’ (SUs) transmission power, fading factor, bandwidth and channel availability on the target channel selecting. Accord...
