Abstract : United States Patent. A method for orthogonalizing inputs with respect to each other. The method comprises the steps of : generating a root structure of N inputs having input order 1 to N, where 2 to (m-1) power 2 to the m power and m is an integer 1; inverting the order of the root structure to generate an inverted root structure having input order N to 1; partially orthogonalizing the root structure and the inverted root structure in associated respective decorrelation circuits to remove inputs common to the first 2 to (m-I) power inputs where I=1; splitting off two substructure from the root structure, where the first structure has input order 1 to 2 to (m-I) power and the second substructure has input order 2 to (m-I) power to 1, where I=1; splitting off two substructure from the inverted root structure where the first substructure has input order 2m to 2 to (m-I) power and the second substructure has input order 2 to(m-I) power to 2m, where I=1; partially orthogonalizing each of the substructures in associated respective decorrelation circuits to remove inputs common to their first 2 to (m-I) power inputs, where I=2; and repeating the splitting off steps and the subsequent partially orthogonalizing step until only one input remains, where for each repetition the substructures that are split-off are treated as new root structure and new inverted root structure, and the value identified for I in each step is increased by 1.
