Joint blind signal detection and carrier recovery over fading channels

A scheme of joint blind signal detection and carrier recovery is developed for intersymbol interference channels. Using a blind sequence estimation scheme, the proposed approach does not require explicit channel identification. It shows robustness against timing error and carrier phase uncertainty. The efficacy of the proposed approach is demonstrated in a simulation involving frequency selective fast fading channel with substantial Doppler shifts.
