This paper considers performance and design issues for Turbo Equalizers. Analytic expressions are derived for the mutual information convergence point of the turbo equalizer. The BER is then found analytically. Results are obtained for both fixed and fading channels, and in conditions of both perfect channel state information as well as unknown estimated channels. Finally, we introduce design rules for adaptive turbo equalizers based on our analysis. The rules give optimal combinations of pilot rate and code puncturing, for a range of fading and SNR conditions.
