摘要

Device (110) to determine information for the time alignment of a first information signal (SDEG (t)) and a second information signal (SREF (t)), having for successive sampling instants in each case one or more data values, with means (120) feature extraction for extracting features (Mi, j, deg) of a plurality of characteristics per sampling time or per subsequence of sampling times of the successive sampling instants to from the first information signal (SDEG (t)), for each feature a first changing characteristic (Mj, deg) which is subdivided into a sequence of time windows comparison, and to extract features (Mi , j, ref) per sampling time or each per subsequence of sampling times of the successive sampling instants from the second information signal (SREF (t)) to obtain by each feature a second changing characteristic (Mj, ref), means being configured (120) feature extraction to select for each time window of comparison a characteristic with higher probability of success of search from the characteristics, having characteristic properties, compared with properties characteristic of other characteristics indicate a greater likelihood of success search looking for the first evolution of feature (Mj, deg; Mj, ref) in the respective time window of comparison in the second changing characteristic, namely with either a scattering amplitude characteristic or a magnitude of a maximum of a similarity measure between the first and second evolution characteristic feature as a measure of the probability of success of the respective search feature; and means (130) for determining the information for temporal alignment based on similarities between the first (Mj, deg) and the second evolution of feature (Mj, ref) characteristic most likely successful search by a search first changing characteristic feature of the most likely successful search in each of the plurality of comparison time windows in the second characteristic changing property most likely successful search.
