Abstract

Cognitive radio is considered as the highly promising solution to the shortage problem of the frequency resource. In this report, we propose the dual-stage spectrum detection method for achieving the wideband, fast, and widedynamic-range spectrum detection. In addition, the success probability of detecting the vacant frequency spectrum and the detection time of it are evaluated by computer simulation. As a result, the simulation shows that the dual-stage spectrum detection method can achieve a highly successful probability of detecting vacant frequency spectrum as well as a small detection time. Therefore, the proposed detection method can be expected to establish high-speed spectrum detection in cognitive radio.
