Adjustable observation window length equalization detector for cooperative communication under frequency selective channels

In this paper, an adjustable observation window length (OWL) equalization detector for cooperative communication with amplify-and-forward (AF) relay under frequency selective channels is proposed. In view of the channel profile difference to system performance, the proposed detector can adaptively adjust the OWL according to the specific channel profile. The numerical results verify the ability of OWL adjustment of proposed detector and show that the proposed detector outperforms fixed OWL equalization detector.
