| Abstract(in English) | An OFDMA based channel access scheme was proposed for dynamic spectrum access to utilize frequency spectrum efficiently. However, it has some problems as follows; the OFDMA based scheme has large PAPR and it needs a receiving filter to extract subcarriers to be used because the designated subcarriers suffer large interference from adjacent channel signals in FFT processing on the receiving side if the OFDMA signal with the same parameters is not used for the adjacent channel. To solve these problems, this paper proposes a novel dynamic channel access scheme using overlap FFT filter-bank based on single carrier modulation. It also shows performance evaluation results of the proposed scheme by computer simulation. |
