Abstract(in Japanese) (See Japanese page)
Abstract(in English) A carrier-sensing method for dynamic spectrum access (DSA) is proposed, which is utilized in the OFDM transceiver with DSA. The proposed method regards the OR of several comparison results between the spectrum intensity of overlapped FFT and an threshold as the carrier-sensing per subcarrier. The performance evaluation result shows that the proposed method achieved 72% of the detection rate with 50% of overlap rate. The proposed method can be inplemented with the only 8.3 % increase of the OFDM transceiver circuit with 100 MHz clock frequency, 40 MHz sampling frequency and 50% overlap rate.
