  • Adaptive demapper
    Patent number: 10164715
    Abstract: An adaptive demapper adaptively demaps an input symbol. An input symbol is received and demapped in a hard-output demapper to generate a current detected symbol corresponding to a constellation point on a current constellation closest to the input symbol. A corrected inverse of a current noise power estimate is determined by updating a previous noise power estimate based on a difference between the input symbol and the current detected symbol. In a soft-output demapper, a log likelihood ratio corresponding to the current detected symbol is determined based on the corrected inverse of the current noise power estimate. The constellation point in the current constellation corresponding to the current detected symbol is then updated to generate an updated constellation based on a difference between the constellation point and the received input symbol.
