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 (m1) 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 (mI) power inputs where I=1; splitting off two substructure from the root structure, where the first structure has input order 1 to 2 to (mI) power and the second substructure has input order 2 to (mI) 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 (mI) power and the second substructure has input order 2 to(mI) 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 (mI) 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 splitoff are treated as new root structure and new inverted root structure, and the value identified for I in each step is increased by 1.
