Abstract(in English) | A dynamic spectrum access to efficiently utilize the unused frequency in a time or space has been drawing a great deal of attentions to improve the frequency of utilization efficiency. To implement dynamic spectrum access in a real system, a flexible dynamic channel access technique, which can change the bandwidth and a channel frequency flexibly, is required. An OFDMA based dynamic channel access scheme and a single carrier modulation based scheme using filter bank are proposed for dynamic channel access. However, the OFDMA based dynamic channel scheme has a drawback of large PAPR(Peak to Average Power Ratio) as it is a multi-carrier modulation technique, and the single carrier modulation based scheme using a filter bank also has a drawback of large amount of signal processing since per channel FFT/IFFT is required. To solve these problems, the authors have been proposing the spectrum splitting channel access scheme using overlap FFT filter-bank. This paper evaluates PAPR performance of the proposed scheme and compares it with the conventional schemes. |
