WebbOrdered Walsh and Hadamard Transforms • Modified versions of the Walsh and Hadamard transforms can be formed by rearranging the rows of the transformation matrix so that the sequency increases as the index of the transform increases. • These are called ordered transforms. • The ordered Walsh/Hadamard transforms do exhibit the property of Webbbased on the Cooky-Tukey-type fast Hadamard transform (FHT) al- gorithm, 2) the computational effort is identical to the conventional FHT, and 3) the transform remains its own inverse. Certain properties of a Hadamard matrix of order N= 2-w make it a convenient vehicle for the computation of the fast Walsh transform (FWT) [ 11, [2].
