ABSTRACT
A unified matrix treatment is presented for the various orderings of the Walsh-Hadamard (WH) functions using a general framework. This approach clarifies the different definitions of the WH matrix, the various fast algorithms and the reorderings of the WH functions.
INDEX TERMS
Fast Walsh-Hadamard transform (WHT), Hadamard matrices, Kronecker product of matrices, recursive matrix factorization, sequency reordering, unitary matrices, Walsh functions.
