Fast Computation of the Discrete Fourier Transform Rectangular Index Coefficients
Saulo Queiroz, João P. Vilela, Benjamin Koon Kei Ng +2
In~\cite{sic-magazine-2025}, the authors show that the square index coefficients (SICs) of the -point discrete Fourier transform (DFT) -- that is, the coefficients $X_{k\sqrt{N}…
