| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Cognitive radio is considered as the highly promising solution to the shortage problem of the frequency resources. In this report, we propose analog Fast-Fourier-Transform (FFT) processer with CMOS switched capacitors for achieving wideband, fast, and low-delay spectrum detection. In addition, the operation speed against desired calculation accuracy is evaluated by computer simulation. As a result, a computer simulation shows that analog 4-point FFT circuit with CMOS switched capacitor can achieve a high speed calculation in wideband spectrum. Therefore, the proposed FFT processer can be expected to achieve high-speed spectrum detection in cognitive radio. | |
