| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | As a spectrum sensing scheme for dynamic spectrum access, a periodgram scheme, a multi-taper scheme, and a filter-bank scheme are proposed. The filter-bank scheme is advantageous in hardware implementation complexity since the hardware required for communications can be re-used for spectrum sensing. However, it is difficult for the conventional filter-bank to change the detection bandwidth, filter type and frequency channel since the conventional filter-bank is based on time domain signal processing. This paper proposes a novel spectrum sensing scheme using overlap FFT filter-bank based on frequency domain signal processing, which can flexibly change the detection bandwidth, filter type and frequency channel. In addition, this paper proposes a windowing method for the proposed spectrum sensing scheme to improve the false-detection performance and confirms its improvement by computer simulation. Furthermore, false-detection and miss-detection performance of the proposed spectrum sensing scheme are compared with those of the conventional periodgram scheme according to the roll-off factor of the filter and modulation scheme. | |
