Systems and methods for multi-level embedded coding and decoding

摘要

A method for multi-level embedded coding may include performing multiple single-level embedded coding operations in order to code multiple types of information. Each single-level embedded coding operation may include coding a second type of information and embedding a first type of information into the coding of the second type of information. Embedding the first type of information into the coding of the second type of information may include determining a desired symbol distribution for a modulated codeword corresponding to the second type of information such that a symbol corresponding to the first type of information is more prevalent within the modulated codeword than other symbols.
