The author considers some generalizations of the discrete Fourier transform and the discrete Walsh transform. The discrete Chrestenson-Kronecker transform is generated by a matrix which is a Kronecker product of Fourier matrices. The discrete Chrestenson-Lévy transform is generated by a matrix which is a new direct product of Fourier matrices. The author studies the properties of both discrete Chrestenson transforms and presents corresponding fast algorithms. Numerical tests and applications are not given.
