Abstract :
In UWB systems, the data symbols are transmitted and received continuously. This study developed a continuous flow parallel memory-based FFT processor (CF-FFT processor) for UWB (ultra wideband) applications. Results show that the developed CF-FFT processor takes approximately 1.31 mm2 to achieve a throughput rate of 1 GS/s, where TSMC0.18 um 1P6M CMOS process was employed.
