In the 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 applications. Results show that the developed CF-FFT processor takes approximately 2.62 mm2 to achieve a operation rate of 1.096 GS/s (Gega Samples per second), where the TSMC 0.18 um 1P6M CMOS process was employed.
