| 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. When a spectrum detector with nonlinear front end detect variety of electric field strength, it can detect false alarm and miss detection because of harmonics, intermodulation, and gain suppression. In this report, we evaluate false alarm and miss detection for a spectrum detector with nonlinear front end by computer simulation. Consequently, the computer simulation result shows that false alarm and miss detection probability are suppressed sufficiently under three-times oversampling, if a dynamic range of 83 dB for the detector. |
