Kronecker Product Factorization of the FFT Matrix
May 1971 (vol. 20 no. 5)
pp. 590-593
M. Drubin, Interstate Electron. Corp.
A method is presented which utilizes the results of the Glassman paper [1] to factor the FFT matrix in terms of Kronecker product expansions [2], [3]. The method clarifies the Glassman results and presents them in an elegant and compact format.
Index Terms:
Compact matrix notation, discrete Fourier transform, fast Fourier transform, Kronecker product expansions, mixed radix.
