Radix-2k delay feed-back and radix-K delay commutator are the most well-known pipeline architecture for FFT design. This paper proposes a novel radix-22 multiple delay commutator architecture utilizing the advantages of the radix-22 algorithm, such as simple butterflies and less memory requirement....
