Abstract(in English) | Overlapped FFT has been proposed as a signal detection scheme in dynamic spectrum access to reduce the variance of the noise and improve the detection probability. However, the improvement of the detection probability in the conventional overlapped FFT is bounded with the upper limit of the overlap ratio. This report proposes a new overlapped FFT scheme using additional frames. In the proposed scheme, in addition to the conventional FFT frames, new frames that consists of multiple subframes with on-continuous samples are constructed and included. It can realize the increase of the number of FFT outputs and the improvement of the detection probability compared with the conventional scheme. Numerical results through computer simulation on indoor channel models show that the proposed scheme improves the detection probability. In addition, it is clarified that as the delay spread increases the detection probability reduces due to the correlation between the frames. |
