Performance improvement by windowing technique in overlap FFT filter-bank for cognitive radio

Abstract (in Japanese) (See Japanese page) 
(in English) For the purpose to achieve higher spectrum efficiency, the authors proposed a flexible channel access scheme using overlap FFT filter-bank based on single carrier modulation for dynamic spectrum access. In order to use idle frequency spectrum on a secondary basis, it is required to further reduce ACI (Adjacent Channel Interference) to avoid harmful interference to/from the primary users. Application of windowing technique to overlap FFT filter-bank is a promising approach to reduce ACI. This report describes performance improvement by windowing technique in the overlap FFT filter-bank and shows frequency response and ACI performance of the overlap FFT filter-bank.
