A Simple Method for Determining Hadamard Sequency Vectors
June 1988 (vol. 37 no. 6)
pp. 743-745
A simple method for determining the sequency ordering of any row in any Hadamard matrix directly from its binary representation is developed. This proposed method is proved to be much simpler than the well-known bit-reverse inverse Gray code method.
