Abstract:
A method for generating a codebook to encode embedded information is described. A distribution pattern of symbols is determined. A first number of codewords associated with the distribution pattern of symbols is determined. A subset of codewords from the first number of codewords is selected. The subset of codewords is included in the codebook if the subset of codewords satisfies predetermined performance criteria.
