ARGUMENTAL EXPRESSION OF CORRELATION FUNCTION BETWEEN ARBITRARY CODEWORDS.

An argumental approach is introduced for an expression of correlation functions between two arbitrary codewords. The real parts of the correlation values are mapped onto the argument vector, then the components of the vector are plotted on a unit circle by each angle. The imaginary parts are expressed on the another unit circle by the same manner. The distinctive features of the proposed method are described in comparison with recent expression methods, and some examples of the application are demonstrated along with numerical results. The argumental expression is shown to be a generalized way to indicate correlation functions for all possible codewords.
