| Abstract(in English) | Cognitive radio is considered as the highly promising solution to the shortage problem of the frequency resource. A spectrum detector that can detect signals of a variety of electric field strength at the same time is necessary to observe whether the specified frequency spectrum is occupied by the other system or vacant. The two-stage detecting method is proposed for these requirements. But, because of error detection by a detector having non-lmeriy and quantization noise, a dynamic range is limited. In this report, we evaluate that a dynamic range can have low error detection probability by the computer simulation. In addition, with this dynamic range, the success probability of detecting the vacant frequency spectrum and the detection time of it of the two-stage detecting method are evaluated by computer simulation. As a result, the computer simulation result shows two-stage detecting method can achieve the high successful probability of detecting vacant frequency spectrum as well as the short detection time. Therefore, the proposed two-stage detection method can be expected to establish the super high speed spectrum detection in cognitive radio. |
