A Generalized Orthogonal Transformation Matrix
February 1979 (vol. 28 no. 2)
pp. 147-150
D.K. Cheng, Department of Electrical and Computer Engineering, Syracuse University
A procedure is described for generating a two-parameter orthogonal transformation matrix which reduces to the Fourier and Hadamard transformation matrices under special conditions. This generalized transformation matrix is particularly useful for multidimensional signal processing on a real-time basis because it preserves a proper relationship in the transform domain.
Index Terms:
signal processing, Fourier transform, Hadamard transform, orthogonal transform, raster scan
