ABSTRACT
Pipeline FFT processors are used in mobile communication systems and in particular in OFDM-based systems. This paper presents a method for power analysis of pipeline FFT processors. This method applies to various architectures with different radices. It also presents a method for mapping utilization rate onto clock-gating, which results in efficient power consumption.
