A Matrix Laurent Series-based Fast Fourier Transform for Blocklengths N=4 (mod 8)
General guidelines for a new fast computation of blocklength 8m+4 DFTs are
presented, which is based on a Laurent series involving matrices. Results of
non-trivial real multiplicative complexity are presented for blocklengths N=64,
achieving lower multiplication counts than previously published FFTs. A
detailed description for the cases m=1 and m=2 is presented.Comment: 6 pages, 2 figures, 2 tables. Conference: XXVII Simposio Brasileiro
