View the content: Split-radix FFT Algorithms


Name: Split-radix FFT Algorithms
ID: m12031
Language: English (en)
Summary: The split-radix FFT mixes radix-2 and radix-4 decompositions, yielding an algorithm with about one-third fewer multiplies than the radix-2 FFT. The split-radix FFT has lower complexity than the radix-4 or any higher-radix power-of-two FFT.
