Abstract: A method, system and apparatus for mapping a symbol from a N-QAM constellation into a binary bit set, where N is the number of symbols in the constellation, and reducing the length of the binary bit set according to at least one property of nonlinear distortion by generating a lookup table (LUT) address from a LUT address generator, and adding the LUT address to a LUT of size smaller than N{circumflex over ( )}(2M+1), where 2M is the number of neighboring symbols to be stored.
