Abstract: More exact probability of channel encoder input data bits are obtained by utilizing turbo code, which is needed in a maximum aposteriori probability (MAP) decoder, to replace the independent and identically distributed (IID) assumption of this probability in general turbo equalization. From the relationship between the two Turbolike methods, the convergence property of turbo codes in turbo equalization is investigated, and then the appropriate degrees of iteration in inner loop are determined based on certain iteration degree in outer loop.

Key words: Turbo equalization, intersymbol interference , Turbo code
