Channel Availability Analysis of Spectrum Handoff in Cognitive Radio Networks

In this letter, steady-state analyses of spectrum handoff delay and channel availability are presented when spectrum handoff is used in a cognitive radio network. The effects of spectrum sensing time, data transmission time, and state transition rates of primary user signals are studied. Numerical r...
