Variable observation window length blind equalization detector for underwater acoustic communication

Abstract Aiming at the influence of underwater acoustic channel (UAC) profile difference on the performance of underwater acoustic communication, a variable observation window length blind equalization detector (VOWL-BED) is proposed in this paper.Compared with the existing methods, the observation window length (OWL) of navy drapery fabric the proposed VOWL-BED can be dynamically regulated on the basis of a given UAC profile and finally converge to the optimum OWL.We have verified the feasibility of the OWL regulation.The simulation results also here demonstrate that the VOWL-BED can achieve better performance than the conventional invariable OWL blind equalization detector (IOWL-BED).
