1. A delay assessment device that receives quantized reference-point values and quantized reception-point values wherein each combination pair of quantized reference-point values and quantized reception-point values is associated with a quantized state, the delay assessment device comprising: an associating unit for associating a predetermined significance value with each combination pair of quantized reference-point values and quantized reception-point values based on the quantized state of that combination pair; a computing unit for computing average weighted significance values for each candidate delay in a set of candidate delays by weighting said predetermined significance values and then averaging said weighted significance values, wherein each pair of said plurality of combination pairs is represented by a quantized reference-point value evaluated at a first time instant and a quantized reception-point value evaluated at a second time instant, where the first time instant and the second time instant are time shifted by the candidate delay; and a selector for selecting an estimated delay time from the set of candidate delays based on the computed average weighted significances.
