This paper describes the design of Fast Fourier Transform (FFT) for the Eureka-147 DAB system. We investigate several possible FFT implementations based on the single butterfly architecture, including an in-place memory structure, to minimize the hardware requirement. We also describe a unified approach toward partitioning the whole memory into several banks so as to increase the equivalent memory bandwidth between the memory unit and the butterfly unit, which can be implemented in either radix-2 or high-radix arithmetic. Implementation results demonstrate the applicability of our work to the targeted channel demodulator and the advantages over previous solutions.
