초록

Ultra wideband (UWB) system is one of the promising solutions for future short-range communication which has recently received a great attention by many researchers. In this paper, we proposed 128-point low power FFT structure based on the memory for UWB systems. The proposed structure can improve implementation area and power consumption efficiency as it consists of one of the butterfly PE and a little memory.
